I am new with Proxmox.

I have seven UCS C220 M4 servers that I use as workstations for running Windows 10 desktops. My employees also utilize these Windows systems, and overall performance is smooth. I'm particularly fond of Proxmox, but one constraint I face is that I can only run about 10 VMs per server without experiencing a slowdown.

Here's an example of the server specifications:
  • 24 x Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz (2 Sockets)
  • 256GB RAM
  • 1Gbit/s network (IP Transit)
Currently, I have about 10 Windows 10 virtual machines set up, to which people connect via RDP. The work they perform is relatively basic, primarily involving web browsing. Once I exceed roughly 10 VMs, performance starts to degrade and things become noticeably slower.

Each VM has 6 cores and 16 GB RAM.

I was wondering if someone can tell from the experience if this is real hardware limit?
