File Copy Eats Ram
 
Hey All

i'm having a problem when copying files from 1 HDD to another in XPx64
The data is read off the source HDD, _into ram_, then when the ram is full
it writes it off to the other HDD

This has never happened to me on any other version of windows, or any other
computer, i'm at a total loss as to why this happens

However, because its doing this it practically stops the computer because
everything is pushed out of ram, and nothing else gets any processor time

Any help would be apprieciated

See the thread entitled "XP x64 - starved for RAM when handling large
files?" I started on the first of this month. Are the symptoms similar to
what I've described?

This sounds suspiciously like http://support.microsoft.com/kb/920739/en-us
for which there is a patch for Windows 2003. You may want to look at the
cache counters in perfmon while this is occurring. If this is the same
issue, call PSS see if MS has or is working on a similar patch for XP.

Re: File Copy Eats Ram
 
This does sound very similar/the same

I tried updating my drivers last night; however this doesn’t appear to have
made any difference

I’ve run HDTach on the drives and they appear to be going at the right
speed, in-fact I even timed the file copy, and it wasn’t overly slow.

However, because it pushes everything out of ram, everything else stops, and
if you try and do 2 file copy’s at the same time the machine won’t really do
anything, and the copy’s take an exponential amount of time longer

That problem does sound very much the same

What do you mean by "You may want to look at the cache counters in perfmon
while this is occurring" (i assume something in taskmanager -> performance)

Where would i find the numbers for PSS?

Thanks for the help

Re: File Copy Eats Ram
 
cache - lazt write flushes, lazy write pages, data flushes, data flush
pages.
memory - page faults/sec

You're looking for "For example, if you are copying a file that is 1 GB, 500
MB of the file is copied to the cache before the Cache Manager starts
flushing the dirty pages. Flushing 500 MB of dirty pages causes several page
faults. These page faults must be committed to the disk. When this occurs,
it can cause bottlenecks on slow disks."

Start run perfmon. Click the "+" to add counters.

Re: File Copy Eats Ram
 
Cheers for the instructions

When idle, i have about 20 Page Faults, up to about 100

When i copied a 4.5gb file, it jumped to 2.5k up to about 3k

Im guessing this is probably my problem then?

(Sorry for taking so long to respond, but ive been quite busy)

Cheers

Oh, also, the Pages/sec are about 12-15k

This looks like the same problem indeed. I would contact ms and see if they
have a similar hotfix in the works for XP.
