Wow.
I bet you'll see a much bigger performance improvement from this on
Windows in particular.
I bet so, too. Traditionally, filesystem calls are painfully slow on
Windows.
But I cannot test before Monday, so I would not be mad if somebody
else
could perform some tests on Windows.
Here are timings for Windows XP running in a virtual machine on a
Laptop. The work tree contains 7k files. I stripped user and
sys times because they are apparently meaningless for MINGW.
Best time before:
$ time git commit >/dev/null
real 0m1.662s
Best time after:
$ time git commit >/dev/null
real 0m1.196s
The absolute time improvement is obviously larger, although the
relative improvement is slightly smaller than in Linus' example.
And here are the timings for the host system, which is Mac OS X,
on the same work tree.
Best time before:
$ time git commit >/dev/null
real 0m0.571s
user 0m0.332s
sys 0m0.237s
Best time after:
$ time git commit >/dev/null
real 0m0.463s
user 0m0.273s
sys 0m0.186s
Interestingly, the relative improvements are even smaller on Mac
OS X.
