Re: Disk thrashing with paging file

Thanks. I'll trying reconfiguring the page file. Unfortunately adding
memory is out of the question due to the number of machines affected.

You might try using a fixed sized paging file set the maximum allowed
instead of letting Windows manage it. This should keep all the paging
file in a fixed location so it is not scattered all over the disk. Also,
as Mark Yudkin says, add memory. 256 MB is truly marginal.

I have the following problem with the paging file on Win 2000 workstations
(256 MB / SP3 / Single physical disk) running our custom user interface
app
(VB6) and SQL Server. During periods of user inactivity Windows pages
out memory and, when the user starts using the app again, there's a long
period
of disk thrashing while memory is paged back in. Analysis has indicated
that neither our apps or SQL Server is doing anything at the time to
trigger or inhibit
the thrashing. (However alot of this problem is due to the fact that our
user interface app holds lots of data in memory. The app uses a further
50 VB6 COM DLLs.)

Apart from the obvious (Reducing memory usage of our apps / Using
recommended page file size & optimising for foreground apps / Optimising
SQL Server / Disabling un-needed O/S components / Reducing disk access /
Upgarding hardware) is there anything that can be done to shorten the
disk thrashing period? Will using SetProcessWorkingSetSize or
VirtualLock APIs make a difference?
