Subject:Multi-threaded MySQL?
View as plain text  
I'm using 3.23.47 on a FreeBSD 4.5 server with two CPUs.  I believe I've got
MySQL configured appropriately to take advantage of this configuration, but
it appears that it only ever uses one CPU.  The other is always idle, or
running the few remaining Unix processes when they want to do something.

I've got these lines in my /etc/my.cnf file, for example:

set-variable    = thread_cache=8
# Try number of CPU's*2 for thread_concurrency
set-variable    = thread_concurrency=4

Is MySQL unable to use extra CPUs beyond one, am I just confused, or is
something misconfigured?
