CPU recommendation

Help!
1

Hi all, would like to setup a new haproxy server for high performance. It will be bare metal, dedicated server. Few questions:

  1. Will CPU 1x Intel E5-2620v4 (2.1-3.0Ghz, 8C/16T) provide enough performance?
  2. Add another CPU, 2x CPUs will be better?
  3. used to run Multi-process mode, like:
    #nbproc 4
    #cpu-map 1 0
    #cpu-map 2 1
    #cpu-map 3 2
    #cpu-map 4 3

Based on docs, it’s recommended to use nbthread, can also keep the bind-process into frontend section?

Thank you all
