Hi, I have a site that runs on IIS7.5 hosted on a windows 7 workstation (Too keep costs down) - its a touchscreen information stand
Now the site runs lightning fast loading pictures (resized using graphics class), ajax queries to load up images from onmouseovers, and it runs like lightneing until I do anything with sessions (1 page uses them for an onscreen keyboard), as soon as you go to that page and hit any letter something happens that slows down image / ajax loads for the rest of the site.
Resource manager doesn't show any spike in usage, SQL is perfectly happy, and the problem can be resolved by setting session timeout to 1 minute or by closing / opening the browser, but ideally I'd like to know why doing anything to a session proves to be such a performance hit, or is it simply a case of go to server / just kill all sessions after 1 minute.
