we have windows 2003 server with 4 prossers xeon 3 ghz. on this server we are
running my company's testing SW called "interlab". we can access this server
via web access. on this we have many test cases, each page shows 100 test
cases. if i want to see test cases  from 101 -200 then i have to go next
page. if i click on the next page then it takes 18 sec just for opening the
next page. cpu takes 25%. we i have on this system 4 cpus are there all are
showing the same graph. we have 4 gb ram and no workload, i am the one who
accessing the both systems.

But if i did on XP system then it takes only 5 secs.

from where i have to start for fixing this propblem? and thanks in advance
for your. help
