Hi,

Primary Site Server High CPU Usage - IIS Worker Process for WSUSPool.

Below is my note when I troubleshot WSUS.
If WSUS logs show nothing particular, you may try to increase memory for WSUS pool

WSUS logs;
- wsyncmgr.log
- WSUSCtrl.log
- WCM.log
- In SCCM> Monitoring> System Status> Component Status>
-SMS_WSUS_CONTROL_MANAGER
-SMS_WSUS_CONFIGURATION_MANAGER
-SMS_WSUS_SYNC_MANAGER

Notes:
-NETWORK SERVICE and Local Users group need to have at least Read permsisions to Wsus Content folder.
-If Sync to upstream server fails, check IIS> Application Pool> WsusPool, increase private memory to at least 4GB and restart WsusPool, then restart Wsusservice to resync
-Increase the WsusPool Queue Length to 2000.
-Increase the WsusPool Private Memory limit by 4 times, or set it to 0 (unlimited).
