Latest cvs-fast-export benchmark
This is the profiling sumary from cvs-fast-export's latest
run against netbsd src, on a Xeon E5-2660 v3 @ 2.60GHz:

That is 3 hours and 30 minutes, which is better than I was expecting.
Some of this is Laurence Hygate's memoized-sort patch; some of it is
me successfully reducing the working set, and some of it is building
with -march=native (this is exactly the kind of code for which that
is most effective). It's almost exactly twice the throughput of my
And it's a factor of ten better than your numbers. Yeah, I guess we'd
better try to figure out why.
There's scope for reducing that time further. Running over an SSD
would, I estimate, knock it down to about two hours. The "Great
Beast" I plan to build, based on a 3.5GHz Xeon ES-1650, might
cut it to one hour and small change.

The Xeon-based proposal is the third one. We have enough donations to
