PC is super fast except when doing large copy operations.

[Guest]

My PC has a Intel i5 quad core @ 2.8 GHZ
4 GB memory
2 x 1 GB - fastest drives I've ever owned

Everything is lightning fast except when I'm doing large copy operations. Like today I messed up my VirtualBox machines so I deleted them from my F drive and copied my backup on J back to F. While doing so, opening a browser, displaying a webpage, any thing really slowed down dramatically. It's like the CPU or memory where maxed out but they were hardly being used. See sequence of screenies...

Sorry. I goofed on this one with the columns visible.

Here's my Speccy report.

Anyone have a clue what's going on?

If your browser cache shares drive with J or F then I wouldn't be surprised. Anyway the drives should be fast on the 4K benchmark for browser cache.

You should also inspect your PC with sysinternal tools, autorun, procmon, procexp are my preferred.

If you were on 2003, this would be your cure (or alleviation). It doesn't apply to XP, but I think it's the same problem - while filesystem cache in RAM fills up, everything is normal, then when the actual heavy duty writing occurs, everything slows down. Additionally, XP uses more of the page file (or in different way).

LargeSystemCache might help, but "setting the value of this entry to 1 is not recommended for computers running Windows XP Professional" according to Microsoft.

I would just wait it out.

Maybe doing a couple tests with a tool like Killcopy:

with different buffer sizes could help in finding a "good" setting to avoid the "general slowdown" when copying (but still it won't "fix" the actual issue)

Also MS Richcopy might be worth a try:

...being aware that MS' Copy/Paste "passes through" your User-Temp folder before reaching the Destination (AFAIK)...

I have rich copy and will test it. I'm doing it now with TeraCopy and seems better. It was in the comments section of the first technet link. Still notice that accessing my start menu folders makes a delay in displaying them.

EDIT: Hmm. Maybe not. My sendto menu is quite large and when I went to upload this via a postimg.org upload utility in send to it took a good second to display the menu....

I would avoid TeraCopy as the pest, latency for copy/paste is a joke, and horrible 4K performance, plus you cannot ctrl+z it. The good thing about TeraCopy (or other for instance) is "control" not speed precisely.
