I have Sharepoint 2010 application that runs smoothly during certain times of day however, whenever it feels like: the CPU usage hits 100%; the ASP Request Execution Time indicator flashes a warning; the Processor Queue Length indicator flashes a warning and the Memory indicator flashes a warning.
Sometimes, not a single warning is flashed.
I have been using Idera Sharepoint Manager
I have increased the cache limit and that seemed to alleviate the problem for a little while. We've also increased from 1 to 4 processors.
The warnings still appear during various times of day and these are not constant. I have cancelled out the probability of timer jobs slowing down the application.
Anyone have any suggestions?
