I already tested it yesterday and the results are pretty much the same (only a very small improvement, which is expected, but not a substantial change). Running top / htop should show if userspace uses all cpu. During the test the CPU usage is this: %Cpu0 :* 65.1 *us,* 5.0 *sy,* 0.0 *ni,* 29.9 *id,* 0.0 *wa,* 0.0 *hi,* 0.0 *si,* 0.0 *st %Cpu1 :* 49.0 *us,* 6.3 *sy,* 0.0 *ni,* 30.3 *id,* 0.0 *wa,* 0.0 *hi, * 14.3 *si,* 0.0 *st %Cpu2 :* 67.7 *us,* 4.0 *sy,* 0.0 *ni,* 24.8 *id,* 0.0 *wa,* 0.0 *hi,* 3.6 *si,* 0.0 *st %Cpu3 :* 72.1 *us,* 6.0 *sy,* 0.0 *ni,* 21.9 *id,* 0.0 *wa,* 0.0 *hi,* 0.0 *si,* 0.0 *st Also note that when I increase the number of CPUs and HAProxy processes I don't get any benefit on performance (and the CPU usage is much lower).
