hawihoney Posted April 1, 2021 Share Posted April 1, 2021 (edited) Don't laugh - just a stupid question: Why shows a passed thru CPU core within a VM less Ghz than the host CPU? Is it because of the emulation? And if yes, is there a way to make a passed thru CPU faster? The host: The client: Edited April 3, 2021 by hawihoney Quote Link to comment

hawihoney Posted April 1, 2021 Author Share Posted April 1, 2021 The host is 2x 2680v2. The VM has 4x cores passed through. The host reports 2,8 GHz and the VM reports 2 GHz. Here we go: TowerVM01.xml Quote Link to comment
hawihoney Posted April 3, 2021 Author Share Posted April 3, 2021 (edited) Found it. It's the Unraid GUI that shows wrong values. Output of cpuinfo within VM. Same VM is reported in Unraid GUI as 2 Ghz (see original post): model name : Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz cpu MHz : 2799.999 Edited April 3, 2021 by hawihoney Quote Link to comment
