excellent response Taz, cheers.  I will work through some of these and see
if there is an issue with any of them.

Sounds to me like that one's a different issue. As far as I know, there's no
real solution to the memory problem except the obvious... if you know that
there's going to be large file operations... slap in some more RAM. Its a
6-inch-nail-through-a-2-inch-plank style of fix, but since memory costs
absolute buttons now, its worth a go.

It may be worth monitoring system resources while running a bunch of file
ops, just to see if the bottleneck is RAM etc. but I can't imagine it is
with 10k file sizes.

I suppose it could be a concurrency issue if there are many files being
uploaded at the same time... then the cure would be to single thread each
upload at a guess, which would of course slow things up anyway.

Other than that... possibly a disk cleanup... defragmenting is not really an
obvious thing on NTFS, but its sometimes necessary. Swapspace is important,
but I'm sure there's something about not having too much. Sridhar has 2048,
which sounds excessive, but I don't know what the system requirements are. I
seem to remember though, that having an excessively large base allocation on
the virtual memory has a negative effect at some point because its got to
index it... I forget these things. I expect there's something on the
Microsoft site that would give some pointers.

The thing is, its all down to individual requirements at the end of the day.
I manage a box that has 20 or 30 sites on it, but nothing running at
millions of page impressions per day... so it doesn't need bandwidth
throttling on sites etc. But you might be running a huge site in a big fat
clustered environment... and then its a whole different kettle of fish on
what hardware and system settings you need.

I've seen some quirky tech problems over the years though. I had to explain
to a manager once that the reason my all the servers were running acheingly
slow, and falling over at any given opportunity, was because he was too
stingy to put air conditioning into a room that was hot enough to bake
pizzas in. I used to have to go in ever morning, open the top window and the
bottom window, set up a fan blowing cold air in through the bottom, and one
blowing the warm air out through the top. Nuts!

I digress... must do some work while there's still time...
