Hi there, was watching hours and hours of awesome videos of @LTS_Tom and learned a ton. -Shout out to Tom!
Coming from vmware (yes, Broadcom is a concern), I was testing XCP-NG to compare it to ESXi 6.7.
Using exact same hardware, Bios settings and absolute basic install of both Hypervisors, I added an identical (again unmodified) CentOS 7 VM and did some speed testing with fio and sysbench.
I notice increases in CPU and RAM speeds for XCP-NG compared to vmware, but the excitement faded quickly when I ran different fio drive I/O tests and XCP-NG delivered about half the speed compared to vmware on identical local PCIe NVME storage.
Testing several other solutions, most of them have some sort of settings like the handling of cache, but I can’t find any possibilities to tweak and hopefully improve the speeds for this XCP-NG host.
Anybody has any idea how to get this resolved?
Thanks!
Robin
