Why is MySQL nearly twice as fast on Linux? (fwd)

[mike]

i'm sending this to the -current list as well.

it seems nobody wants to help take ownership - and i'm trying to
get some sort of incentive going.

i know there are other people out there who can probably contribute more
as well if this can be fixed/resolved.

[please read my reply below]

once again, here's the deal.

i'm willing to PAY someone to own this issue and figure out how to resolve
it. also give them access to my box to do whatever they feel like (it
needs to stay AMD64 - but i don't care if you go up to 5.3, down to
5.2-current, 5.1, whatever)

so i'm supplying resources and incentive. why is nobody stepping up to the
plate to help figure out where the bottleneck is? it *sounds* like it's
threading or the scheduler or a combination of both, i don't know.

but i'm pledging at least $250 USD, and someone else will pledge another
$100 - and that's just two of us.

if someone owns it and can get a fix out in the next week or two (i don't
care how or where) i could even give a bonus.

once again - resources and incentive. let's figure this out so everyone
can benefit. i just want to expedite this effort.
