New submission from Wolfgang Dobler <[EMAIL PROTECTED]>:
I find that darcs2 takes ~ 60 times longer to do `darcs w -ls' on a largish
real-life SVN tree. Here's some timings:
prompt> rm -rf _darcs ; /usr/bin/darcs init ; time /usr/bin/darcs w -ls >
/dev/null
6.912u 0.232s 0:07.22 98.8% 0+0k 0+0io 0pf+0w
7.188u 0.296s 0:07.52 99.3% 0+0k 0+0io 0pf+0w
prompt> rm -rf _darcs ; darcs2 init [--hashed] ; time darcs2 w -ls >
/dev/null
396.504u 2.352s 6:52.75 96.6% 0+0k 0+0io 0pf+0w
446.899u 2.480s 7:49.69 95.6% 0+0k 0+0io 1pf+0w
386.548u 2.276s 6:37.59 97.7% 0+0k 0+0io 0pf+0w
prompt> rm -rf .hg ; hg init ; time hg add > /dev/null
0.856u 0.244s 0:01.11 98.1% 0+0k 0+0io 0pf+0w
0.888u 0.240s 0:01.11 100.9% 0+0k 0+0io 0pf+0w
My darcs versions:
prompt> /usr/bin/darcs --version
1.0.9rc1 (release candidate 1)
prompt> darcs2 --version
2.0.0pre3 (unknown)
[static binary downloaded from the web site]
The tree I am trying to import contains 6467 files (mostly Java + Python) of ~
42 MB in total.
The file sizes have the following statistics:
average size = 6.5kB
quartiles:
0% (=min) : 2 B
25% : 712 B
50% : 1.8 kB (= median)
75% : 4.8 kB
100% (=max) : 1.6 MB
I cannot give access to the data, but if nobody else has found this type of
slowdown, I could try to synthesize directory trees with similar statistics.
