Hello,

I have a strange issue: While I'm debugging, the performance for a function that loops trough 20 rows at client side is correct (1 second approx.) , but when I deploy on a very powerful server and I'm accessing the published web site with the same computer and browser, it takes almost a minute to iterate trough all rows.

The only workaround I've found is to reset all IE8 configuration so it goes back to 1 second again, but in production (ok)...

I'm sure that the problem doesn't have nothing to do with settings in advanced configuration nor security configuration nor compatibility mode, because setting the defaults for any of them separately does not fix the problem (of course I reboot IE after doing changes).

What could be the setting for this ? I need to be sure that the other 60 pcs with IE8 we have on our company to set up will work flawlessly, and I cannot reset IE8 on all of them because they have specific configurations. Also, I cannot upgrade Infragistics components right now because I don't have enough time to do it right now...

This is very frustrating because while I was developing, I thought it'd run 10 times faster in production with more powerful client pcs and no debug code, but this is not the case (except if I 'reset' IE8 config).

Thanks in advance !
