Subject: I made a flame graph renderer for git's trace2 output
Date: Fri, 10 May 2019 17:09:58 +0200
Message-ID: <> (raw)

Here's a flamegraph of where git's test suite spends its time on my box:

I hacked up a script for this today to plot trace2 production data, as
noted there it's at:

What are flamegraphs? See

As noted in TODOs in the script there's various stuff I'd like to do
better, and this also shows how we need a lot more trace regions to get
granular data.

But it's already quite cool, and I'll keep improving it. I'll submit a
PR to Brendan's parent repo once I'm happy enough with it, I figure it
makes more sense there than in git.git, but maybe we'd eventually want
to teach the test suite to optionally use something like this.
