Hello, I have an interesting problem which I have been unable to solve. MySQL seems to only use 1 core at a time with my current config. I've never noticed this before. I installed MySQL from the OpenSolaris repo's as I recall. This is on my personal box and it's been a while since I've tried to resolve this issue. How can I get mysql to use both CPUs? Attached is my mysql config.
SunOS plur 5.11 snv_111b i86pc i386 i86pc Solaris
Status of virtual processor 0 as of: 09/15/2009 20:15:52
on-line since 08/10/2009 18:15:09.
The i386 processor operates at 2010 MHz,
and has an i387 compatible floating point processor.
