After installing a number of HPE/Aruba CX switches I was finding that they were completely unresponsive to SNMP requests. Went through the config and couldn't see anything... Eventually found that you need to configure this line in order for the SNMP service to run: snmp-server vrf default Don't forget to do a "wr mem" afterwards!
Was configuring WSUS on a Server 2016 VM for a customer recently and found the performance to be very sluggish and most of the time the client PCs would time-out and throw an error message when trying to check for updates. After much digging on different forums I came across a fix that worked nicely: Open Internet Information Services (IIS) Manager and click on Application Pools Then Right-Click on your WsusPool instance and choose Advanced Settings Scroll down to Private Memory Limit (KB) and change it from the default of 1843200 to 0 which means unlimited. Then right-click and stop the WsusPool and then start it again. Hope this works for you.
