Martin and I have revamped the benchmarking test suite concept, we pair
programmed a small an fairly elegant tool to let us have benchmarks.
I'm merging it into bzr.dev now (it has two +1's :)).
To use it, just do 'bzr selftest --benchmark -v'. We probably should
make -v default to on.
This will run the benchmarks and report how long they take. Our first
one is for 'add'. In the output there are two numbers:
This lets you write (for instance) a benchmark that tests the
performance of commit on 10K files without it being conflated with the
performance of add on 10K files.
To make something in a benchmark test accrue time to the benchmarked
operations counter, run it via self.time.
I.e. "self.time(self.run_bzr, 'add')" will run self.run_bzr('add') and
have that timed.
The time is not reentrant safe: if you time a routine that times things,
the time will be added twice. The intent is that the operations being
timed should always be in the benchmark test itself, for clarity of what
is being tested, so this should not be a significant issue.
