bzr-explorer performance question

[Maritza Mendez]

Repeating the original experiment, but from the command line instead of
bzr-explorer:

bzr init-repo SHARED_REPO
cd SHARED_REPO
bzr init trunk
cd trunk
# copy all 5000+ files and 300+ directories to trunk
bzr add   # takes 2.9 seconds
bzr commit -m "start project"   # takes 142 seconds, very reasonable for the
work done
bzr stat  # 22 seconds
bzr stat  #  less than 1 second


So... we see that the first bzr stat after the commit takes much longer than
the second and third, but still nowhere near the 4.5 minutes typical of the
first bzr stat in bzr-explorer after the same commit.

Perhaps fstat/lstat is creating a fundamental effect, but something else
seems to be happening in bzr-explorer.

And to be fair, I should test qbzr as well, since that may be the real
reason bzr-explorer takes 4.5 minutes.

Meanwhile, I need to think about how to write this up in a bug report.
Suggestions are welcome.
