With all of my fixups applied I took some performance measurements
today from two of my larger day-job repositories:
A.git (356 branches):
Current Fetch New "Builtin" Fetch
------------------ --------------------
real 3m19.921s real 0m9.969s
user 1m58.050s user 0m1.449s
sys 2m4.747s sys 0m4.465s
B.git (24 branches):
Current Fetch New "Builtin" Fetch
------------------ --------------------
real 0m21.250s real 0m4.735s
user 0m10.981s user 0m0.510s
sys 0m12.387s sys 0m1.481s
All runs were a no-op fetch over SSH on the LAN. The system running
git-fetch was a Cygwin/Windows 2000 box and the server was Solaris 9.
Just starting an SSH connection (`ssh solsrv echo hi`) takes me on
average 1 second so a 4.7s no-op fetch on the smaller repository
is very respectable.
3m19s vs. 9s? I'll take 9s, thankyouverymuch. Even if I have
more testing and debugging to do. Especially since the two repos
above are only a sampling of the actual set I have to deal with on
a daily basis.
