From memory: It was FreeBSD 4.9, FreeBSD 5.2, DragonFly (3/17/2004), Linux 2.4.25, Linux 2.6.5, and NetBSD 1.6.2. About all I remember were that things were fairly even except Linux filesystem performance was better (I think both XFS and ext3 were benchmarked). Not earth-shattering stuff, but there were a few interesting points (that now escape me). In any case, sorry for the noise.
