Subject: [PATCH v9 0/3] read-cache: speed up add_index_entry
Date: Tue, 11 Apr 2017 19:16:59 +0000 [thread overview]
Message-ID: <20170411191702.20134-1-git@jeffhostetler.com> (raw)
From: Jeff Hostetler <jeffhost@microsoft.com>
Version 9 addresses the following:
() p0006 perf test can now run using either synthetic repos
from t/perf/repos/many-repos.sh -OR- an actual real-world
repo.
() The commit message has been updated to include results of
p0006 on linux.git.
() Line 0006.3 shows a positive value, but results for that
line had a lot of variance between runs. I measured the
blocks of code I added and they only added 0.007 to 0.015
seconds. I suspect the overall time difference and variance
is due to file I/O to update the worktree when switching
branches.
I think this version has addressed everything raise so far,
so I think I'm ready to let this one rest. Thanks for all
the help and feedback.
