Selective disk cache?

I have a setup where PC 2 regularly copies a large quantity of files from PC 1 (for backup). It's flushing out the disk cache on PC 1 and making other functions sluggish. Is there any way to tell PC 1 not to cache files that are requested over the network?
 
This reg tweak may help. Doesnt stop using all you memory for caching, but
should make your system more responsive when you copy those files.

open registry editor
goto [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\
Memory Management]
Look for "DisablePagingExecutive" change is value to 1 (Note Hex 1 = Dec 1)
0 is the default setting
1 stops the core of windows from being paged to disc
 
It's already 1! (Note I've just installed SP2?) Although it's not any faster since.

In a similar situation when copying large files between physical discs,
system would become very slow as the file cache filled up and everything
else was paged to VM, the reg tweak helped a bit. There a product that may
help

I'll give the free trial a go, and I like the sound of the "data safety" thing - adjusting the time before writing to disk, but all it seems to be doing is adjusting a few settings which presumably could be done by hand in the registry - for a paid-for program I'd expect something a little cleverer, like not caching files the first time round - eg if I copy 1GB of files I do NOT want them cached, but I DO want files cached that are read a couple of times - like data files in use by an application. I'm not after freeing application memory, I'm after geting my disk cache back without it getting flushed all the time! I can't believe how thick XP's cache is.

He was deeply in love. When she spoke, he thought he heard bells, as if she were a dustcart reversing.
 
Question - what is correct here?
http://80.229.155.158/temp/cache.gif

I have 2GB of RAM, and Clevercache is reporting 1GB free, 1GB used, and 0.3GB cache (which by simple mathemsatics must mean that the cache is included within either free or used.
Yet the task manager reports 1GB free and 1.4GB of cache?!?
What are the true figures?

In a similar situation when copying large files between physical discs,
system would become very slow as the file cache filled up and everything
else was paged to VM, the reg tweak helped a bit. There a product that may
