Just ran a small test on my old box - very interesting result.
Definitely IO bound. iotop gives me 4-6 M/s, sometimes 99.99%. CPU
mostly around 20-30%, with some jumps to 70-80% or so. 8G mem full.
Swap about half full [but lots of pgms running]. 2 cores, one core
often gets very near/at max, when CPU is high, but usually sits at
about 60-70% visually [using htop].

I didn't think of this until your note, but looks important. Thanks!
