I have been looking around for ways to speed up page load times on a client site I am working on. We already use all the standard tweaks and offload all images to a CDN service etc and the performance is ok but I have today stumbled across a site not related to DNN but they talked about some changes that can be made to the web.config that helps with performance and I have to say the pages appear to load quicker. Now I have not done any testing at this time but thought I would post it up for others to see.

 <httpRuntime executionTimeout="300000" maxRequestLength="2097151" requestLengthDiskThreshold="25819200" useFullyQualifiedRedirectUrl="true" shutdownTimeout="300000" requestValidationMode="2.0" minFreeThreads="88" minLocalRequestFreeThreads="76" appRequestQueueLimit="5000" enableKernelOutputCache="true" enableVersionHeader="true" enable="true" delayNotificationTimeout="5" waitChangeNotification="0" maxWaitChangeNotification="0" enableHeaderChecking="true" sendCacheControlHeader="true" apartmentThreading="false" />

yeah, I understand what you are saying but can tell you that "visually" the site / page load times are quicker. I need to do some load testing to see if it has any downsides but would like to see if people would try the changes to see if it has any effect on their site but it was noticable immediately and if I comment the line out and revert to the DNN 6.x default the site became page load became slower so it is doing something. I am using PowerDNN shared hosting so it is difficult to know what positive or negative effect is might be having on the CPU/memory/disk etc.
