Don't worry, I'm on that.  I'm already having enough problems with 
database performance under Linux, if they start killing results on the 
easy benchmarks I'll really be in trouble.

The thing I was alluding to is that both FreeBSD and Linux kernel 
developers are now doing all their PostgreSQL tests with sysbench, a MySQL

tool with rudimentary PostgreSQL sup****t bolted on (badly).  I think 
rather than complain about it someone (and I fear this will be me) needs 
to just fix that so it works well.  It really handy for people to have 
something they can get familiar with that runs against both databases in a

way they can be compared fairly.  Right now PG beats MySQL scalability 
despite that on read tests, the big problems with PG+sysbench are when you

try to write with it.
