Performance tracking

[Ludovic Courtès]

Hello!

I was looking at the “history chart” at
<http://hydra.nixos.org/build/2517280#tabs-history>, which shows graphs
of the build time and installed Guile size vs. commits.  Timings must be
taken with a grain of salt, because of variability on the build machines.

Still, a couple of worthwhile observations:

  • commit 1af6d2a (“Minimize size of embedded syntax objects in
    psyntax-pp.scm”) reduced the installed size from ~14.6 MiB to
    ~13.3 MiB;

  • CSE led to a build time increase from 28m at
    <http://hydra.nixos.org/build/2413477> to 43m
    <http://hydra.nixos.org/build/2478518>.

Thanks,
Ludo’.
