Update Panel Slowness - IIS Hosting - Production Server

Hi

I am having a page with 10 update panels & each update panel has mode a conditional & diff trigger points.

It works very fine when I test on my local using Visual Studio.

Once I host my code on production server & IIS 7.0 & page starts taking 20-30 seconds on minor actions like show/hide fields based on down drop selection.

Production server is much more powerful than my local machine, I am not sure why its very slow.

Is there any setting under IIS server or I am using too many update panel. But strange behaviour is that its taking 1-2 secs on my local machine.

Thanks in advance !!!

Regards
