From 47f6aef02b85c604bbd556574e2c724b7304e9e8 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Fri, 4 Jan 2013 22:29:22 +0000 Subject: configure: allow building without getrusage Measuring the resource usage of threads is moderately expensive since it requires doing an additional system call everytime a thread context switches.
