It's also running on our firewall with pf and the performance is quite nice, less than 10 % utilization. I have a NFS-server running 5.3 beta 3 which is accessed by the webservers. The volume is lightly accessed. Next week it will host a new volume which will have a lot of activity, so I'd like to upgrade it to 5.4 RC2 before that (saturday). Looking at the only major problems left, I feel pretty comfortable that RC2 will be very stable. The NFS-server is a Compaq dual PIII at 1 GHz (G2), 3 GB RAM, Smart RAID 5 (ciss), qlogic 2310 hba and an Intel GBIC-card (em). The em-driver is mpsafe and the isp-driver is not, but overall the performance should be better with 5.4 compared to 5.3. Has anyone had the opportunity to compare NFS on 5.3 and 5.4? Should I play it safe and wait until May before I upgrade? regards Claus
