Wow! That. Is. It.
Toggling malloc debugging option J makes the "slow" machines "fast"
and vice versa.
Athlon 64 X2 5200+ 2.6 GHz, FreeBSD 8.0-CURRENT amd64 ~60 min
19 seconds.
I guess that falls under the "obvious" configuration differences
to check, but since it usually doesn't cause a significant slowdown
I completely forgot about it. Embarrassing.
But still. Two orders of magnitude? That is a pathological case.
Probably it means that lzo2 is doing pathological numbers of mallocs.
