From: Karsten Blees Date: Fri, 20 Jun 2014 21:07:14 GMT Subject: [PATCH v6 06/11] trace: add current timestamp to all trace output Message-ID: <53A4A282.20209@gmail.com> In-Reply-To: <53A4A195.1070502@gmail.com> This is useful to tell apart trace output of separate test runs. It can also be used for basic, coarse-grained performance analysis. Note that the accuracy is tainted by writing to the trace file, and you have to calculate the deltas yourself (which is next to impossible if multiple threads or processes are involved).
