I've been using Aptana for some time now, and as of recent I've been dealing with files that are really, really big (500+ lines of code, which is huge for me, being a novice developer). Whenever I deal with smaller files, I get that weird sensation that I'm "in front of" what's typing, but now I'm quite sure of it--there is a significant lag between when I type something and when I see the text appear on screen. I don't have this issue with Dreamweaver CS3, so I know my computer has the capability to edit these files without this happening, but Eclipse still lags.
I also don't see when something is being deleted if I hold down backspace, I see the first few characters get deleted, but then everything "hangs." Once I release the backspace key, the characters that would've been shown deleting instantly vanish all at once. The same thing happens with the forward delete key.
I'm beginning to think this is an issue with Java, since I have the same feeling that everything is slightly "behind me" when I'm using -any- Java application.
The computer is an intel Pentium 4 3.2 GHz Prescott, with 2GB's of DDR400 RAM and a Radeon HD3650 graphics card.
If anyone knows how to fix this lagging issue, I'm all ears (eyes?); if anyone can recommend a different IDE with capabilities similar to Aptana (I do Python, HTML, CSS and JS; I use Git for SCM), I'd be glad to give it a try. Thanks!
I'm running a brand new iMac i5 with 8GB RAM and an SSD and Eclipse is slow as hell. I don't know if upgrading your machine is really the solution to your problem.
In my case Aptana also was very slow while typing, and it helped to choose

I bet You have default amount of memory assigned to Eclipse in eclipse.ini file - go there and increase those values 2-3 times. Eclipse will work much faster.
Aptana is a great software, but you're facing one of it's disadvantages: it's a memory hog.
I'm using Aptana in a 4gb machine, but I remember having the same lags using the same configuration in your example.
If you can't live without Aptana (and Eclipe plugins), I suggest you to buy more RAM and use a HD that's at least 7200 RPM. I'm running in a Vista Machine and it works flawlessly.
If you can live without Aptana, check other Python IDE's in "What IDE to Use for Python" question right here in SO.
My 2 cents: I've used PyScripter for Python, and it's great. PyScripter with notepad++ is a good and fast choice.
Good luck!
I'm using the most recent version of Aptana (3.1.3.201205292243) and had this exact same problem. Increasing the memory allotments did nothing for me. The problem goes away, however, if I turn off the Word Wrap option in the editor.
This is found in:
Window->Preferences->Aptana Studio->Editors->Enable Word Wrap
I know, it's a stupid fix, but it works. :)
Luck, everyone!
I have the exactly same problem. Eclipse with Aptana Studio installed is really slow and not usuable for developing. Increasing the memory did not help at all. But what actually help (at least as far as I can tell until now), was to delete the Aptana log files as migg proposed.

Is there a way to identify what's going on with Eclipse when a file is saved?
My eclipse runs extremely slow (takes close to 3 minutes to save a file). Simple addition of a space in a file and save, it keeps saying 'Updating Navigator Content Viewer' and 'Remote System Explorer Operation' and simply freezes.
I am running on a powerful system with 16 gigs of ram and assigned 1 gig for eclipse. The way it performs is simple unacceptable and planning to switch all my projects to NetBeans rather than wasting hours on save.
Any hints on fixing this are appreciated.
Finally resolved the issue by getting rid of Eclipse.
Moved all my projects to NetBeans 8.2. Its a big relief to see my projects getting saved in a split second.
Coming to Eclipse, it is powerful and exceptional on all aspects other than the slowness during save. However, this frustrating issue alone makes me rate Eclipse 1 (may be 0) on a scale of 10. Cannot expect a developer to wait for 2 minutes to save a file (on a 16 gig system, with 4 gigs assigned to Eclipse) which would drag the productivity drastically.
Looks like this issue is not something new as I have seen many posts on various forums regarding the same. I don't understand how Eclipse never gave a thought on this slowness issue.
First you should try to look at this post so:
Check if it is the latest version (I personally run Neon 4.6 and it takes about 2 minutes to parse and save a 55MB file)
Check your JDK/JRE
You should also try to see if it doesn't come from your drive...
If you still have the problem, I suggest you look at the other Eclipse versions (Mars...)
I have had this problems for a couple of times but usually could solve it by an update. However, this fix does not work for me anymore.
Actually, two problems here:
The minor one: I have osX 10.8.3 and Eclipse Juno (M20130204-1200) installed. Since a good amount of time, it takes eclipse ~ 4-5 minutes to start up for the first time after the system start. Once it was closed and is re-opend again, it starts up quick. I think this problem came since apple started to mess around with the JRE? Does anybody also experienced this delay? Could it be that one of the installed plugins checks for updates and causes the delay?
The major one: after eclipse is fully up & running, I can not open .py files anymore. When I open my pydev project (btw. pydev 2.7.3), eclipse freezes and I need to kill the whole thing and restart. -> I can not use it for python coding anymore, which is my primary task...
Suggestions? Re-install eclipse maybe?
Thank you for suggestions,
El
Can't really comment on #1, but for #2, can you try attaching jvisualvm to see what's going on there? (and create a thread-dump and post it somewhere so that I can take a look at it).
I'd ask you to create a bug-report for that, but the new tracker is still not up (I hope I'm able to put it up right after the funding at http://igg.me/at/liclipse is finished).
The problem was resolved by following these steps. They essentially disable one

I use Eclipse Java EE IDE for Web Developers for most of my coding, html, css, php etc etc. Recently however I have noticed an issue where after doing a combination of "something" the display of my files completely screws up and does all sorts of weird things.
For example if I try and add a on starting to do it the characters just start going all over the place and giving me display issues like that shown in the attached screenshot.
It's a little tricky to explain exactly what's happening but eclipse basically becomes unusable as each keypress seems to do something random and mess up the page even more.
Does anyone have any idea what might be causing this? I'm using a mac on Snow Leopard with Eclipse Indigo.
Just to update this. To resolve this issue I ended up downloading the latest version of eclipse and overwriting the eclipse directing with this. I tried just doing an update but this did not work so I'm guessing I had some corrupt files or something.
The good thing about eclipse is that you have a workspace folder that is essentially separate, so if you replace eclipse you can just re-import your old workspace.
ALl seems to be working as normal so far!
I am using Eclipse for Java development. I have a number of plugins (Maven, Subversive, JBoss reverse Engineering tools, etc), and the system seems to hang fairly consistently, to the point where it can be 10-20 seconds from a mouse click until it responds. I have given it a gig of memory in the configuration, and it is not even using half of that. When it hangs, it completely pegs one of the processors, and I see large numbers of Page File Deltas.
Is there any way to see what is happening inside Eclipse? Which plugin could be causing the problem?
I believe (although I am not positive) I am running Eclipse 3.5.2. I am running on Windows XP, SP 2 or 3 (I do not manage the machine, my company does, so I am not positive how up to date it is).
First, the one plugin that can help investigation this would be MAT (Memory Analyzer).
Full tutorial at Vogella.
Second, make sure to use an optimized eclipse.ini launched with the latest JDK (6u22) and check if the issue persists then.
I use Eclipse for programming in PHP and Java(Android) and sometimes Python, unfortunately Eclipse is nowadays much more often freezing.
Often when I write this bracket "[" for defining an array in PHP, Eclipse just freeze and I have to close it manualy and start again.
I've noted also, that Eclipse is consuming really much of my RAM... 200-300MiB of my available memory is nothing special. :-(
Is there any way to check, what is consuming the memory in Eclipse and why it's freezing?
I'm running on Windows Vista, 3GB RAM.
Start eclipse with -consolelog option.
Start by looking at the error log. Under Windows → Show View → Other → Error Log. See if you can find any errors.
Another option is to try starting with a new Workspace (File → Switch Workspace). You can easily import your existing projects and see if the problem persists.
I would also recommend upgrading to PDT 2.2, which is part of the upcoming Helios release (Eclipse 3.6).
First thing, make sure that you have the latest version of Eclipse. Second, you can turn off things like automatic building, reporting problems as you type, content assist, and you can turn off the "Link with Editor" on the outline view to boost performance. The drawbacks, of course, are that you won't have those features.
As your code grows, with these features turned on, your performance decreases.
The memory range that you report can be normal, depending on the size of your code. However, the memory shouldn't continue to grow if you're not adding to the code.
I haven't witnessed any memory leaks in the latest version of Eclipse.
I was experiencing long delays with Eclipse on a large PHP project before I upgraded to a dual core processor.
