Re: AW: Performance Problems, probably network related



I often found claims that PV is old and slow. The newer PVH is much faster. I can not confirm that. In my testings PV was as fast as PVH.

Yes I am also satisfied with PV and it's even faster at boot-time because there's less of a machine skeleton to setup. However I understood it's more about security and reduced attack surface so at least for a public cloud use-case PVH seems preferable for domUs.

I do not pin vcpu for dom0 but rather enable higher priority for it (default is 256) and simply keep sharing all the cores.
