Nice work!

I think it would be equally interesting if you posted benchmarks for 
MySQL 4.1.x
Since the last post comparing MySQL 5.x vs 4.1.x on FreeBSD showed that 
MySQL 4.1 series had almost double the benchmark performance numbers 
over 5.x MySQL
I couldn't bare the idea of using MySQL 5 if its still only half as fast 
and has features I don't need.
I believe most people would prefer 4.1 unless they really need the 
features that are in 5.x or don't need performance at all.
