Actually - In our test if just used with a similar load as pgbench (e.g. typical web applications) Mac OS X 10.4.7 performed better then Yellow Dog Linux (I was testing with G5 hardware) on the same hardware as soon as more than about 90 concurrent clients were simulated.
At this point, that's just an interesting historical note. Yellow Dog is not a particularly good Linux compared with the ones that have gotten years worth of performance tuning for Intel/AMD processors. And you really can't extrapolate anything useful today from how it ran on a G5--that's two layers of obsolete. The comparisons that matter now are Intel+Mac OS vs. Intel+a popular Linux aimed at servers.
As an unrelated note, I'm curious what you did with pgbench that you consider it a reasonable similation of a web application. The default pgbench transaction is very write-heavy, and the read-only option available is way too simple to be realistic. You'd need to pass in custom scripts to execute to get something that acted like a web app. pgbench is an unruly tool, and there's many ways to run it that gives results that aren't so useful.
