Need help with Windows VPS
Hello,
I have hypervisor with the following specs:
Intel Xeon D 1520 / 4c/8t / 2,2 - 2,6 GHz
64 GB of RAM DDR4 ECC 2133 MHz
And I have there 30 Windows Server 2012 (KVM based) VPS created all with 2 cores, 2gb ram and 30gb disk and they are not running any resource intensive apps but are all online and for example browsing internet. Management panel is virtualizor.
The issue is that hypervisor is always at 100 / 100 / 100 load and high CPU usage and VMs are very very slow taking forever to load for example speedtest in chrome.
Is there any tip or trick to do here to optimize this so these VPS can work faster? Any effective and smart suggestion is very useful and thank you for your help in advance.

What's causing the load? You need to figure that out first before you can find a solution.
Are they all doing Windows Update? I'm assuming this was recently created/done since its not specified
Nothing specific has causing the loads and they are not performing Windows update. I have created these VMs myself these are not clients. VMs arent doing anything intensive.

your CPU simply isn't strong enough for that amount of windows VMs. you have 4 Cores running like 60, what do you expect? also network connection maybe limiting and causing higher load (assuming this is an OVH HOST-64L guaranteed bw is 250mbit/s).
bam to hell your TE business plan goes.
end of story.
TE tech support makes me miss Nike /24 IP request posts
Also are you running virtio on these vm's also a good practice for windows I have found it to have disk caching set to writeback I know this is not CPU bound however it may help your VMs be smoother
What type of disks do you have?
Load would also be high if alot of swapping is going on.
