Why is MySQL nearly twice as fast on Linux/AMD64 Vs. FreeBSD/AMD64?

[mike]

i don't know if this is any idea - but why isnt something like
linuxthreads ported to amd64? i would think with the 64-bit architecture,
it could be even better than the i386 version.

again, i am threading-retarded, so if getting linuxthreads working on
freebsd 5.x on AMD64 is "not appropriate" because freebsd 5.x is supposed
to have it's own better threading library now, then just ignore me; but it
seems like linuxthreads has always been the fastest implementation on
freebsd. i'd be willing to put $$ towards accelerating the effort to get
mysql performance on freebsd 5.x AMD64 better. i don't know what the best
setup is, but whatever needs to be done and a way to patch/reproduce it.

i know that JG is interested in this [VERY MUCH], i am interested in this,
and i believe i've seen another few posts of other people trying to figure
this out as well...

thanks,
mike
