    I have an X3421 Gen10 Microserver w/ stock 8GB RAM running Windows Server 2019 Eval. I did the standard install, then added HyperV and container support. This isn't part of a domain - nothing is set up beyond the initial install and normal Windows updates. The boot disk is an MX500 SSD attached to SATA5 with 2 4TB 3.5" drives in the cage. I was seeing ~20% CPU utilization for the SYSTEM process and ~22% for SYSTEM INTERRUPTS. I tracked that down to the vEthernet device. When I uninstalled HyperV and removed the vEthernet device it dropped down to ~12.5% CPU for SYSTEM and ~2.5% CPU for SYSTEM INTERRUPTS. Note that this is looking at the task manager performance tab. If I right click on SYSTEM and select Go To Details it shows SYSTEM taking about 6% CPU and SYSTEM INTERRUPTS taking about 2%. I don't know what causes this discrepancy. Running LatencyMon (for about a 30 second run) shows Highest measused time: 343 Highest reported ISR time: 33.8 (storport.sys) Highest reported DPC time: 212.3 (ndis.sys) Total hard page fault: 26 I'm not sure how to track down the source of the SYSTEM process CPU usage. I don't see anything unusual in the event logs. Truthfully I'm more concerned about the SYSTEM CPU usage, but both seem high to me for a server that is basically just sitting there. Is there something strange going on or is this just the cost of running Server 2019 on a relatively low performance CPU? This server is replacing Home Server 2011 on a MediaSmart EX495 and idle CPU on that was about 3-5%. I have installed bios ZA10A360, chipset driver WS2012R2_W8_1, AMD Chipset Graphic Driver 17.1.1, and the Broadcom NX1 driver (cp031155) - all from the HP site. Not sure what else to try. Is this normal for Server 2019 with no load? Thanks in advance for any advice, -Jim
