From 3fcb10e496505e5573a7fc386cd1152781d37fe6 Mon Sep 17 00:00:00 2001 From: Mark Drayton Date: Tue, 4 Dec 2018 12:34:20 -0800 Subject: perf tools: Allow specifying proc-map-timeout in config file The default timeout of 500ms for parsing /proc//maps files is too short for profiling many of our services. This can be overridden by passing --proc-map-timeout to the relevant command but it'd be nice to globally increase our default value. This patch permits setting a different default with the core.proc-map-timeout config file parameter.
