From a9031675b9f757eef0fe8c99284ec0133c032c32 Mon Sep 17 00:00:00 2001 From: Gabriel Kerneis Date: Tue, 17 Sep 2013 18:26:48 +0200 Subject: coroutine: fix /perf/nesting coroutine benchmark The /perf/nesting benchmark is broken because the counters are not reset after each iteration. Therefore, nesting is done only on the first iteration, and skipped on every other. This patch fixes the issue, and reduces the number of iterations to make it possible to run the benchmark in a reasonable amount of time.
