HAProxy進程間統一平衡

Question

我們用於nbproc 10多進程 HAProxy。採用 Intel(R) Xeon(R) CPU E5-1650 v3 @ 3.50GHz 的伺服器。

在配置中：

  nbproc 10
  cpu-map 1 0
  cpu-map 2 1
  cpu-map 3 2
  cpu-map 4 3
  cpu-map 5 4
  cpu-map 6 5
  cpu-map 7 6
  cpu-map 8 7
  cpu-map 9 8
  cpu-map 10 9
  stats socket /var/run/haproxy/socket1  process 1
  stats socket /var/run/haproxy/socket2  process 2
  stats socket /var/run/haproxy/socket3  process 3
  stats socket /var/run/haproxy/socket4  process 4
  stats socket /var/run/haproxy/socket5  process 5
  stats socket /var/run/haproxy/socket6  process 6
  stats socket /var/run/haproxy/socket7  process 7
  stats socket /var/run/haproxy/socket8  process 8
  stats socket /var/run/haproxy/socket9  process 9
  stats socket /var/run/haproxy/socket10 process 10

我們觀察到一個大差異率進程之間：

請幫我解決這個問題！

嘗試將負載平衡演算法更改為 lessconn 而不是 roundrobin。
