FreeBSD blah.blah 7.0-CURRENT FreeBSD 7.0-CURRENT #2: Tue Jul 17 12:31:02 CEST 2007 Seems stable here, just survived a buildworld -j4 + basic load (mysql-server, apache, imapd, fetchmail, procmail, spamassassin) without problems. Interactivity was very good throughout. CPU: AMD Athlon(tm) 64 Processor 3500+ (2210.77-MHz 686-class CPU) It's a uniprocessor system running an i386 kernel.
