Client CPU goes up while browsing asp.net with ajax page for long time

[Mamun]

My application is developed in asp.net with c#, measurment studio, ajax. It has around 100 network veriables which read data from SVE in every second and shows the value. While browsing the application from the client using IE7 for long time and kept the browser untouched for more than 1 day the cpu goes 50% consumtion in client pc. And hence the Page responds slowly. But if I refresh the page manulay the cpu consumption goes down and works fine.

The page also contains two webform graphs.

Any solution to reduce client cpu consumtion or why does it happen?

Thanks,

Mamun

Mamun,

Have you seen this (the performance section) DeveloperZone document on using SVE efficiently?  Are you using these practices?
