[pve-devel] [PATCH 1/2] add hugepages option

[Alexandre DERUMIER]

>>Is it worth to use 1GB pages?

for big vm memory, yes (database of 100-200GB).
I have seen 20% improvements

Also (but I need to verify), dpdk doc said that it need 1GB hugepages.

(I think it's work with 2MB, but performance is very degraded)


I have almost finish to rework my patch, I'll try to send it today.

Which leads to the next question: 

Is it worth to use 1GB pages?
