Hi!
Yes, that is what our core is. Early on I redid much of the IO
handling code to make better use of it. It is not perfect though... I
need to move around the IO code to tweak a bit more out of it.
BTW I am surprised you found a multi-core benchmark where is was
worse. Even for MySQL whenever we tested it, it came out on top.
Though... with 4 core you set it to what, 2? The other threads, like
Innodb's, are not counted in that number.
Cheers,
-Brian

Do you have the thread pool code in your tree

Have you done anything to make it efficient?
For me, sysbench OLTP readonly is up to 3X faster using blackhole when
pool-of-threads is not used -- http://bugs.mysql.com/bug.php?id=42288,
and this is on a 4 core server so I assume the overhead gets much
worse with more cores.
