I have changed the vm config file according your suggestions after of apply
your patches:
numa0: memory=124416,policy=bind
numa1: memory=124416,policy=bind

And always with:
...
sockets: 2
cores: 20
cpu: host
hotplug: 1
memory: 248832

...

Anyway, the change was for much better. ... :-)
...Many thanks for the patches !!!

Maybe qemu 2.2 optimisations ? If you don't have change vm config file, this
can be the only explain.

Many thanks for your reply, and please, let me to do a question:
Then, why I have a great difference of performance between the before and
the after of install your patches if i never touched the kernel nor his
configuration? (the patches installed are: pve-qemu-kvm_2.2-2_amd64.deb and
qemu-server_3.3-5_amd64.deb)

Best regards
Cesar
