Hi, my DNN sites have been loading ok until 1st April. They usually load initially within 15 seconds. Now it takes around 15 minutes to load. This happened before I updated to v8. problem didn't fix after installing v8.

Has anyone experienced the same?

I ran proc mon and noticed that file loading to cache doesn't happen continuouly like my other server where DNN works just fine. around 1000 files are loaded and then no file movement, obviously no DB movement as files are still loading to the cache. Then say another 1500 is loaded and then nothing happens for few minutes and so on until around 15 minutes is passed when it finally loads. Once it's loaded pages are very fast as usual. Now if I go to a new area in the Admin then it's slow again for the first time. 

I uninstalled and re-installed IIS but that didn't help. 

Same files copied to my other server works like a charm pointing to the same database.

Any clue?

Thanks.

Thanks Sebastian for your prompt attention.

No, there were no changes to the file system. Only thing I can recall is there were some server updates pending for a while and that day I decided to run them all and restarted the server few times.

I feel like it's an IIS issue as I can see files are loaded to cache in one stretch in server 1 but in this server it stops at some point and idle for 2-3 minutes and loads again. therefore I uninsulated IIS completely and re-installed it. Still same results. FYI.. all the pending windows updates are re-installed now.

I tried uninstalling few latest updates earlier but that didn't really helped.
