Of late we are facing High CPU whenever there is a save or publish.We were able to find out that Sitefinity calls are locking the thread.
Hence no other request is being Processed.It doesnt get released until there is a IISReset or App Pool refresh.
We increased the CPU in the server but still didnt help.
We found that Diagnostics module was activated in the Sitefinity in the LIVE environment but there was no setup done.So we disabled that.
But we are still facing the issue.
We are seeing errors in Sitefinity error log and trace log but nothing that points to High CPU.
Also we are not able to figure where the errors are happening (that are being recorded so much in the Error Log).
Just a brief background:Our team was not involved in the Sitefinity website setup of my client.We took over it from another team and we have not worked on it much since.
This is the information with regards to the thread lock. I have highlighted the main details in the trace.
