Looks pretty nice. The small graph is pretty cute.

I wonder about having columns that you can expand. When you have a
couple hundred columns it is a little bit difficult to find what you
want. But sometimes you might want to expand a certain region, to find
what revno introduced a performance hit.
Like I think the performance jump for:
InvBenchmark.test_make_10824_inv_entries
between 1839 and 1859 was probably caused by my

1851 (jam) support mac-normalization for unicode files.

Since it now has to do a unicode normalization check on filenames to
make sure you aren't adding non-normalized filenames. For performance, I
would be willing to special case the code so it only gets called if we
are on Mac OSX.

But it would be nice to know that for certain.

You also have every 10, but you are missing 1849.
