TS-1365 Added a little more help on how to avoid wasting CPU
> specifying -t option doesn't seem to have the desired effect on epoll timeout

> In normal operations we see {{traffic_server}} using around 2.5 % while idle.
> The assumption is that it's doing a lot of {{epoll_wait()}} - increasing the
> timeout (~10000) with {{-t}} *increased* the CPU load. Setting it to the
> default (10) has no affect - as expected. Setting it to 0 gives us 100% CPU
> usage (as semi-expected).
