History
Tom Weininger baefc3b464 Set nohz_full in cpu-pinning element 
nohz_full (or full dynticks) is a Linux kernel setting that should reduce
kernel noise on configured CPUs to a minimum. This change activates this
setting on all vCPUs except the first one.

Element to enable optimizations for vertical scaling

This element configures the Linux kernel to isolate all but the first vCPU of the system, so that they are used by HAProxy threads exclusively. It also installs and activates a customized TuneD profile that should further tweak vertical scaling performance.
