Boris Feld <boris.feld@octobus.net> [Thu, 22 Nov 2018 21:00:13 +0100] rev 40750
perf: add a perfignore command The command is meant to benchmark operations related to hgignore. Right now the command is benchmarking the loading time of the hgignore rules.

Tue, 20 Nov 2018 17:44:24 +0000 perf: disable revlogs clearing in `perftags` by default
Boris Feld <boris.feld@octobus.net> [Tue, 20 Nov 2018 17:44:24 +0000] rev 40747
perf: disable revlogs clearing in `perftags` by default This aligns things with what `perfbookmarks` does. I decided to disable the revlogs clearing by default to focus on the core logic by default, ignoring side effects. If we prefer to emphasize the side effect, we can instead keep this on in `perftags` and enable it by default in `perfbookmarks`.
Tue, 20 Nov 2018 10:55:20 +0000 perf: add a `clear-revlogs` flag to `perfbookmarks`
Boris Feld <boris.feld@octobus.net> [Tue, 20 Nov 2018 10:55:20 +0000] rev 40746
perf: add a `clear-revlogs` flag to `perfbookmarks` This flag (off by default) makes it possible to enable the refresh of the changelog and revlog. This is useful to check for costly side effects of bookmark loading. Usually, these side effects are shared with other logics (eg: tags). example output in my mercurial repo (with 1 bookmark, so not a great example): $ hg perfbookmarks ! wall 0.000044 $ hg perfbookmarks --clear-revlogs ! wall 0.001380
Tue, 20 Nov 2018 10:38:15 +0000 tags: cache `repo.changelog` access when checking tags nodes
Boris Feld <boris.feld@octobus.net> [Tue, 20 Nov 2018 10:38:15 +0000] rev 40745
tags: cache `repo.changelog` access when checking tags nodes The tags reading process checks if the nodes referenced in tags exist. Caching the access to `repo.changelog` provides a large speedup for repositories with many tags. running `hg perftags` in a large private repository before: ! wall 0.393464 comb 0.390000 user 0.330000 sys 0.060000 (median of 25) after: ! wall 0.267711 comb 0.270000 user 0.210000 sys 0.060000 (median of 38)

perf: add a `clear-revlogs` flag to `perftags` This flag (on by default) makes it possible to disable the refresh of the changelog and revlog. This is useful to check for the time spent in the core tags logic without the associated side effects. Usually, these side effects are shared with other logics (eg: bookmarks). Example output in my Mercurial repository $ hg perftags ! wall 0.017919 comb 0.020000 user 0.020000 sys 0.000000 (best of 141) $ hg perftags --no-clear-revlogs ! wall 0.012982 comb 0.010000 user 0.010000 sys 0.000000 (best of 207)
