I am using Eclipse Helios. Last days I am facing problem that Eclipse Helios is taking very much time to launch. When I checked the Task manager, I found that the Memory usage linked to eclipse Helios is growing very slowly and at 31,132 K it stucks and then suddenly it catches a 62,000 K of space and eclipse get launched.
I found the same issue with my other system, So i realized it is something eclipse.
Can anybody suggest me the solution of the same or I need to format my system.
My System Configuration-
Windows XP , 4GB Ram , i5 Processor
Adding more , as soon as I open the eclipse , immediatly the tray manager shows the eclipse program as Not Responding, then I need to wait for next 10 - 15 mins to get the eclipse launched.
You might be hitting an issue similar to this bug. Check your anti-virus software.
Probably its taking time as it is building the code before launching the application
Click on Windows-->Preferences
Now on the left handside tree Select "Run/Debug-->Launching" and uncheck the "Build(if required) before launching" option
Hope it helps :)

I hope I post that question in correct place.
Since a few days I have a problem with Netbeans 8.2 (fresh installation)
Java 1.8.0_162.
Operating system: Windows 7/10 . The problem occurs on three different computers.
Steps to reproduce:
Open any file in Netbeans IDE (the editing caret is blinking),
Deactivate NB window (click on another window, notepad, browser
doesn't matter),
Back to NB again by clicking directly on opened
document (caret is blinking again),
Now you should notice CPU usage. To make it lower click on "Output" panel.
SOLUTION FOR THIS ISSUE
Found a solution for this problem. I installed older vesion of JDK 8u144 and set netbeans_jdkhome variable in <netbeans install directory>/etc/netbeans.conf, so it points to that version. Now everything works correctly, no CPU usage at idle.
As ImtiazeA noticed Netbeans works fine without this issue with JDK 8u172 installed (thanks for your answer). They must have fixed it :) So just dont use 8u152 and 8u162 and it will be good.
EDIT
Deactivated all installed plugins and still the same problem.
Installed Netbeans 8.0 - didn't help...
Downloaded the Dev version of netbeans and got the same issue. Now using IDE Profiler and got this message:

Someone somewhere said that it's a problem with Tasks pane somewhere in background doing something. Turn it on and then off in Menu/Window/Tasks, and your computer will start breathing again for a while.
For me, Ctrl-Shift-6, Ctrl-W is a new involuntary action.
If they don't fix that in the next seven years, I'm switching to another IDE. That's the maximum I'm giving them.
I have the same problem. What seems to be happening is Netbeans is constantly checking the selected code window for compile and syntax errors, even when Netbeans is minimized. My solution is to not delete the Start Page tab that appears when you start Netbeans. Then before minimizing, select this tab and the CPU usage drops to 0.
For those who did not notice the solution Krzysztof mentioned in the question, I installed another JDK and it fixed my issue. I just installed the latest JDK 8u172 (instead of 8u144) and it worked for me.
Another possible reason: Large amount of data in clipboard.
My NetBeans was consuming more than 70 % of CPU. I followed advice from a comment above and opened IDE Log from View menu. There I got the following error:
java.lang.OutOfMemoryError: OutOfMemoryError at
sun.awt.windows.WClipboard.getClipboardData(Native Method)
Switching to another window, selecting few characters and Ctrl-C resolved the issue.
Just to mention that I work on Intel i5 and Windows10-64bit.
I tried literally everything. After one of those system updates, my Netbeans 8.2 influenced a system to be very slow, almost to the point of unresponsiveness. During NB startup or build, system is practically unresponsive.
So, all possible tweaks both Netbeans and Java, couldn't solve a problem.
It seems that Windows update itself trigger off a problem to happen, as updates did changes on low system level, I suppose.
I decided to lower a Netbeans PID, by creating new shortcut like this :
cmd.exe /c start "Netbeans 8.2 LowPrio" /Low "C:\Program Files\NetBeans 8.2\bin\netbeans64.exe"
For now I can work without disruption, and it's far more smoother, than before.

I found a solution for this. Atleast that worked for me. I was having same issue.
My solution is to remove your netbeans inner folder from AppData and try restarting netbeans. It works perfect now. My path is C:\Users\awais\AppData\Roaming\NetBeans
Remove 8.1 or 8.2 folder and restart netbeans.
I had the same problem suddenly, but the problem was Windows 10 Dark mode, after switch back to Light color scheme on windows 10 it was normal as before.
TIP: You can profile the netbeans and check which consume more resources.
Canceled the unpacking index task that seemed to be stuck. (bottom right of screen)
I've been having trouble getting a weblogic server to run in eclipse, which have resulted in me not being able to open eclipse ni my current workspace at all. It is not my first attempt to work with weblogic servers in eclipse, and I do not know why it suddenly decided to stop working. I have had multiple errors, which all seem to be related to an abnormal high memory consumption.
One of my last errors, before eclipse quit on me for good, was an out of memory exception, on PermGenSpace. I set variables to 1024m, but it still complained it wasn't enough. After a lot of restarts, Eclipse suddenly wouldn't open my current workspace. I have tried others, and they work fine, but with my current one, the splash/loading screen disappears after about 10% of the loading bar is complete, and nothing happens at all. Except the fact that eclipse.exe shows up in the running processes tab on Windows task list. It does not show in the running programs list.
My attempts to start weblogic servers had the exact same symptoms. They showed in the process list, but did not respond when I tried to open the console in my browser.
Both eclipse and the weblogic tasks (shown as java.exe) has had over 400.000KB of memory consumption each, which I find very high.
I do not expect anyone to be able to find a complete solution here, but I am absolutely stuck. I cannot access any of my previous error messages. I have no experience debugging an error like this. Does anyone have any idea on how to find the error in a case like this?
My Weblogic version is 10.3.2, which is a company standard for now.
My Eclipse version is:
Eclipse Java EE IDE for Web Developers.
Version: Kepler Service Release 2
Build id: 20140224-0627
Adding the comment as an answer since it provided some help.
Try starting up to a new empty workspace; If you dont get to select workspace at startup use the argument "-data " If you still get issues, look at the log in /.metadata/.log
My Netbeans has been insanely fast for over 2 years, until this morning. Something strange, however, is now happening. Every time i press "copy and paste" ... so CTRL-C, it goes slow. This is what I see:
So, the moment I press CTRL-C, that shows in the bottom, my entire machines goes into super slow mode, and then 5 seconds later it stops.
I've considered maybe there's a keylogger on my machine, but can't find anything. And it's only slow when I copy and paste from Netbeans, nothing else. Maybe Netbeans is sending data out some other way?
Any ideas why Netbeans would just go slow like this?
UPDATE
I only have one project open
I've disabled the git and subversion plugins
I am working on a Laravel project
It's slow when I copy from a VIEW or when I copy from a CONTROLLER (I know css files often go a bit slow because of Parsing, so I figured mentioning this is probably worthwhile)
I followed the advice at the end of this article: here and uninstalled "BlueStacks". Problem solved.
UPDATE
Just in case the article gets deleted, here is the advice the user gives on that page:
I meet the same problem. When I copy a word in the IDE, the IDE does not response until 2 or 3 seconds. I did not confront this problem until few days ago. I try to use the latest netbeans and the latest jdk, but that does not work. Then I find someone said http://bugs.java.com/bugdatabase/view_bug.do?bug_id=5078787 is the problem. And the problem is somewhat about the COM in windows. So I try to install the netbeans to another Win7 PC, and the problem is gone. In that case, I guess the problem is not the netbeans, but some other application in windows. Later I uninstall some of the application I just installed few days ago. And the IDE works right now. The applications I uninstalled is "imc studio" "imc license manager" and "blueStacks" an android simulator. I guess these application may have influence to the COM of Win7. Hope my solution will help to this bug.
You can also just stop the BlueStacks Agent process from Task Manager while you're using NetBeans.
I am a mentor for a FIRST (usfirst.org) Robotics Team Rotoraptors (http://rotoraptors.webs.com/) and we are using NetBeans (7.4) to create the program for this year’s robot (we chose Java over LabVIEW [i.e. G] and C++). We keep running into the same issue w/ NetBeans:
We install NetBeans and all requiste plug ins from FIRST
We start programming and all is well
Randomly we go to start NetBeans and it hangs on the "Starting Modules" stage.
We are not adding any other modules, updates, or other software. (The laptop we are using is dedicated to programming our robot, so it does not need anything else beyond what we are able to run before the hang up.
We always end up uninstalling then reinstalling NetBeans, after which it runs for awhile until hanging up at the same "Starting Modules" step again
After reinstalling NetBeans we are able to open the same Java project that we were working on before we saved it and turned of the laptop.
I cannot put any related events or triggers to the issue. It just happens at random.
Any and all help will be greatly appreciated by me and the kids on the team.

Next time please create a threaddump, a sampling snapshot of NetBeans (using JVisualVM from your JDK) aand attach it to a new issue at https://netbeans.org/bugzilla/
Do not forget to attach the IDE log too
Perhaps one of the plugins causes a deadlock.
Most recently I have added to NetBeans j2me plugin , then after installation of related J2ME sdk it started stick on that forever "starting modules.."
I simply uninstalled that j2me sdk outside and netbeans now starts ok again.
I use from netbeans 8.02 on windows 7 and my net beans hang constantly and recently i fixed hanging problem just with renaming "component" folder name of netbeans in following path ...AppData\Roaming\NetBeans\8.0.2\config\Windows2Local
when hanging occurred again
I searched lot about this topics but can't find a proper solution.
I am using eclipse 3.6 Helios version with operating system fedora15. In my application I am using GWT2.4 for front end development.
Now while I work with debug mode and want to debug at some point at the same time eclipse hangs for 3-4 mins.It resumes after and again start to debug process.
I am using this eclipse from last 3 years with windows but not faced this issue.In fedora I am using it from last 4 months and this problems stated to occur from last one month.
I am not getting what is the issues with eclipse.
Please help me out.
Thanks in advance.
Is this something that happens with different projects/code, or is it the same code that causes freezes? I've had issues where threads have started in the background and caused problems.
You say "(...) hangs for 3-4 mins.It resumes after and again start to debug process.", what do you mean? Does it continue to debug and move to the next line, or is there a crash and it restarts?
How long has it been since you changed workspace? I've found this, rather than the Eclipse installation, to be an issue over time. Create a new workspace folder, export all your projects and preferences and start fresh.
You are using GWT 2.4 and I think you might be working with UI.xml too... There is a tag in each ui.xml at the top like
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
Which means eclipse is going to get that xhtml.ent file each time and there is a issue in GWT eclipse plugin have a look to below link
http://code.google.com/p/google-web-toolkit/issues/detail?id=5265
There is one comment which says
For me, removing
SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent"
and saving the document,
solves the problem..
maybe it is needed for something, so better you copy that locally somewhere, and link that.
Try it out and let me know.
I had experienced the exact same problem on a less-powerful notebook I had to use.
Try one of the following
Download the latest Eclipse version (It needs, just as helios, a lot of RAM and CPU because it's based on a new "architekture", in contrast to, for instance, galileo)
Make sure you are using the latest JDK and JRE
Download Eclipse Galileo, which does require pretty less resources and goes still very very fine with most projects!
It sounds like you are experiencing the features of the latest Eclipse arch. In the latest versions of Eclipse I have noticed that the more plugins and add-ons you have installed, the slower the environment runs. There are a lot of similar posts regarding performance on the new platform
I have removed all but the plugins I am using and never install anything not needed into the Eclipse environment.
I "may" have experience this. Not sure. Suddenly started working again. I was getting a hang every time I would try to debug an app, in the part of the code (inside GWT) that creates a "table" element. Could be that there is something that just takes a while and you just have to "wait it out" the when it happens. Go get a cup of coffee, type thing. anyway I HAD stepped deep into the GWT code, plenty so I'm convinced it IS a GWT issue of some kind.
I was thinking it was some infinite recursion possibly in the logging system (like logger code accidentally trying to log itself, and going into loop?). Also there's a 50/50 chance that it was simply clicking on 'run' instead of 'debug' made it start working again. So at least try that if you have problems. My gut instinct and 30yrs programming under my belt tells me it's logger related. I can rule out "slow computers" because I never had this happen until I got a new machien which is Dell XPS, Core i7, 8 GB ram, and massive disk. So I wouldn't blame hardware, or Eclipse bloat.
