thx for your answer
i have seen it, and was very helpfull than you four your presentation, we tried vmware esxi and got better results than proxmox, for now we keep on esxi, still not tried hyper-v
we get better performance with core i5 8400 than Xeon e5506, whit proxmox and esxi
but
proxmox had not stable performance with around 1gbps of customer traffic (internet traffic 1500 customers) esxi stable performance tried up to 1500mbps of traffic and rising
i think proxmox requires some special tuning that we do not know, or maybe the NIC drivers have some problem, esxi required manual NIC driver install but ater that works nicely without any special tuning
