hi there,

we are running a win2k3 sp1 terminal server with the usual apps on it - MS
office, acrobat reader, etc. it is a dual cpu xeon with 4gb ram and we
regularly have 40-45 users online concurrently.

however today the server began to run *very* slow to the point of unuable
even from admin console however the strange part was that the cpu and ram
were being reported as hardly used (10-30% CPU and ~2gb ram free). a restart
resolved issue but only for an hour or so. restarted again and now has been
working better for about 2 hours, but every now and then it's like it freezes
for 10-20 seconds then carries on ok.

only thing i have done is install acrobat reader 8.1 and uninstalled iis
(was just a default install and had not been used). has anyone seen such a
drop in performance for no apparent reason?

thanks.
 
Re: strange performance issues

I've seen quite a few posts here lately complaining about
performance issues with Acrobat Reader 8.
That would be my first suspect.

Re: strange performance issues

BW-

Another problem I ran into was the TCP Offload Engine that is being shipped on most Dells
being enabled - we had asynchronous network problems as well as general performance
problems that was a PITA to track down...

Did removing Adobe 8 help you out at all?

Re: strange performance issues

Is the machine slowing down or is it slow only inside a TS session? Did you
collect any performance data on the machine?
