I'm adding some performance logging to ui.write - this benchmark lets us confirm that the cost of that logging is acceptably low. At this point, the microbenchmark on Linux over SSH shows: ! wall 3.213560 comb 0.410000 user 0.350000 sys 0.060000 (best of 4) while on the Mac locally, it shows: ! wall 0.342325 comb 0.180000 user 0.110000 sys 0.070000 (best of 20) diff --git a/contrib/perf.py b/contrib/perf.py --- a/contrib/perf.py +++ b/contrib/perf.py @@ -1269,6 +1269,17 @@ timer(fn, title=title) fm.end() +@command('perfwrite', formatteropts) +def perfwrite(ui, repo, **opts): + """microbenchmark ui.write + """ + timer, fm = gettimer(ui, opts) + def write(): + for i in range(100000): + ui.write(('Testing write performance\n')) + timer(write) + fm.end() + def uisetup(ui): if (util.safehasattr(cmdutil, 'openrevlog') and not util.safehasattr(commands, 'debugrevlogopts')): diff --git a/tests/test-contrib-perf.t b/tests/test-contrib-perf.t --- a/tests/test-contrib-perf.t +++ b/tests/test-contrib-perf.t @@ -109,6 +109,7 @@ perfvolatilesets benchmark the computation of various volatile set perfwalk (no help text available) + perfwrite microbenchmark ui.write (use 'hg help -v perfstatusext' to show built-in aliases and global options) $ hg perfaddremove _______________________________________________ Mercurial-devel mailing list Mercurial-devel@mercurial-scm.org https://www.mercurial-scm.org/mailman/listinfo/mercurial-devel
