Ok, I built the DB library on linux basically the same way I did on Solaris,
(albeit with a different compiler) and got these results:
Threads Shortest Longest Average
4 1:05 3:46 2:27
2 0:39 3:14 1:56
This time having 2 threads seemed to help. Still not even close to Solx86
though.

Interestingly enough, I was having problems with slapd hanging indefinitely.
I rearranged my slapd.conf to keep the sections separate and the problem
seems to have gone away -- thanks for the tip.
Also, it turns out that my entire LDIF is about 10M, so openldap on
solx86 is pushing out about 20MB/s, which seems pretty good to me.
