From b64aa553d8430aabd24f303899cfa4de678e2c3a Mon Sep 17 00:00:00 2001 From: Petr Holasek Date: Thu, 16 Apr 2015 17:38:18 +0200 Subject: [PATCH] perf bench numa: Show more stats of particular threads in verbose mode In verbose mode perf bench numa shows also GB/s speed, system and user cpu time for each particular thread. Using of getrusage() can provide much more per process or per thread stats in future.
