NAME ^

NetServer::Portal::Top - Make event loop statistics easily available

SYNOPSIS ^

  require NetServer::Portal::Top;

DESCRIPTION ^

All statistics collected by Event are displayed in a format similar to the popular (and excellent) top program.

PRECISE STAT DEFINITIONS ^

It is unfortunately that more intuitive stats are not available. Benchmarking is a slippery business. If you have ideas for improvements, don't be shy!

The three load averages are for the most recent 15 seconds, 1 minute, and 15 minutes, respectively.

For efficiency, not all time intervals are available. When you change the time interval, it will be rounded to the closest for which there is data.

BUGS ^

The potential impact of multiple CPUs and kernel-level thread support is ignored.
