Say I install FreeBSD (using default partitions), install MySQL from a package on the CD, run a stress test, collect numbers, then repeat the process with a Linux installed over the previous FreeBSD installation, and find out that FreeBSD allows the MySQL server process 1/3 queries less, what (if anything) will be wrong in my claim that MySQL/FreeBSD is slower than MySQL/Linux? -- How many Vietnam vets does it take to screw in a light bulb?
