Hello EE community,
We host over 600 sites in a farm of 6 servers and on a monthly basis we do a deployment that will overwrite the DLLs in a folder called \BIN which is a centralize point for the binaries of all the site folders. We have a symbolic link to the \BIN folder under each site folder. During the deployment, we run a script on all 6 servers, that will stop IIS, overwrite the DLLs in the \BIN directory then start IIS. The minute this happens, the CPU spikes to a steady 100% which could last up to 3-4hours on all the servers once the first request comes in for each site. I understand that it goes through a "warm-up" process on the first hit x 650 w3wp.exe processes running = CPU spike. The way we get around this is by restarting the servers.This happens on every deployment. Is this normal? If not, how could I troubleshoot this issue to find out what is causing this.
