Proxmox 6.3-3 is successfully installed at my dell r730xd server. After few difficulties, Proxmox Mail Gateway is also installed. Subscription is paid, first days in production looks good. But there is a perfomance problem. After short investigation, I detected that CPU runs at low speed.
- cat /proc/cpuinfo | grep "MHz" shows 1200 MHz in average (varying).
- lscpu shows that this is min speed for Intel(R) Xeon(R) CPU E5-2690 v3 @ 2.60GHz. Max goes to up-to 3500 MHz.
- As I can't reboot to come to bios, Open Manage is needed. But how to install it at Proxmox 6.3-3?
- How to increase/fix CPU speed for specific VM?
