Oh I totally agree - i just came across the 'I've got a paging issue so my
first thought would be to improve the disk' thought which I think shouldn't
start with the 'have I got a fast enough disk' but 'why have I not got
enough memory' :)
Commander Australia! Ah-ha I knew the reason why we lost the burnt stumps
again couldn't have been because our cricketers are rubbish ;)

Hi Andrew,
Sorry, I was mixing threads and trying to address other aspects of system
slowness as well.
I agree 100% that if you haven't got enough free memory things really don't
perform well.
But you can extend things just a bit further by minimising paging and
getting everything else reasonably optimal. Then you obviously also look at
things like unnecessary processes (ctfmon, virus monitor, altiris agent etc
etc) that don't have to run for everyone. 10-15 MB per user x 50 users is
often worth doing.
If we're giving Angela a system makeover, we might as well do the lot ;-)
regards,
Rick

I would start with:
Are you using a SCSI RAID system in your server with a Write-Cache enabler?
