Well, speaking from a practical perspective, Bazaar is still plenty fast
for most projects. I use it every day at work, home, and school. The
largest project I've used it on myself is an ~4000 file, ~200 MB total
file contents project. It works great there, though of course further
speed increases would be great.
While Bazaar is fast enough for most projects and most people, when git
is 10 to 100 times faster for some operations, it simply makes you go
"wow" and wonder what makes git so much faster. Is it because bzr is
written in Python, or is it something deeper, like git's storage

It doesn't appear to me that the performance difference between
Mercurial and Bazaar is particularly significant. Mercurial looks a
little bit faster, but what astounds me is when a VCS is consistently
5-10 times faster than others.

Don't forget that MySQL is using Bazaar successfully.

I know it will. The Bazaar team has a lot of brilliant people on it
and they are constantly improving it.
