Copy files in PowerShell too slow - powershell

Question

Good day, all. New member here and relatively new to PowerShell so I'm having trouble figuring this one out. I have searched for 2 days now but haven't found anything that quite suits my needs.
I need to copy folders created on the current date to another location using mapped drives. These folders live under 5 other folders, based on language.
Folder1\Folder2\Folder3\Folder4\chs, enu, jpn, kor, tha
The folders to be copied all start with the same letters followed by numbers - abc123456789_111. With the following script, I don't need to worry about folder names because only the folder I need will have the current date.
The folders that the abc* folders live in have about 35k files and over 1500 folders each.
I have gotten all of this to work using Get-ChildItem but it is so slow that the developer could manually copy the files by the time the script completes. Here is my script:
GCI -Path $SrcPath -Recurse |
Where {$_.LastWriteTime -ge (Get-Date).Date} |
Copy -Destination {
if ($_.PSIsContainer) {
Join-Path $DestPath $_.Parent.FullName.Substring($SrcPath.length)
} else {
Join-Path $DestPath $_.FullName.Substring($SrcPath.length)
}
} -Force -Recurse
(This only copies to one destination folder at the moment.)
I have also been looking into using cmd /c dir and cmd /c forfiles but haven't been able to work it out. Dir will list the folders but not by date. Forfiles has turned out to be pretty slow, too.
I'm not a developer but I'm trying to learn as much as possible. Any help/suggestions are greatly appreciated.

#BaconBits is right, you have a recurse on your copy-item as well as your getchild-item. This will cause a lot of extra pointless copies which are just overwrites due to your force parameter. Change your script to do a foreach loop and drop the recurse parameter from copy-item
GCI -Path $SrcPath -Recurse |
Where {$_.LastWriteTime -ge (Get-Date).Date} | % {
Copy -Destination {
if ($_.PSIsContainer) {
Join-Path $DestPath $_.Parent.FullName.Substring($SrcPath.length)
} else {
Join-Path $DestPath $_.FullName.Substring($SrcPath.length)
}
} -Force
}
