Hi everyone. I've got a web app that I'm getting ready to make public and I'm to figure out how well MySQL will utilize multiple processors. Has anyone seen how MySQL would scale from 1 to 8 processors? Is it even remotely close to linear? My dev environment is W2K, but production will run Red Hat 9 or Red Hat Enterprise 3 (I know the OS will make a difference in SMP utilization).
My reasoning is this: 1) if it scales somewhat linearly, I could start with a 2-CPU box and upgrade to an IBM440 8-CPU box or similar later when the site membership <prayer> really takes off </prayer>. 2) Otherwise, spray queries over a cluster of 2-CPU boxes. Does this make sense?? If I go with option 2, and have one master (for inserts/updates/deletes) rep to a cluster of slaves(optimized for reads only), how often will the master rep to the slaves? Is it near real-time? I couldn't find where you specify the rep interval. Does that setup make sense for an app that does more reads than writes?? I've searched this forum and the web, but couldn't find much info. Sorry if I missed anything obvious.
