give credit where credit is due. recent NFS benchmarks are almost laughable. time dd if=www2_otherlocal.tar.gz of=/dev/null bs=128k 219+1 records in 219+1 records out 28760021 bytes transferred in 3.411756 secs (8429683 bytes/sec) 0.000u 0.443s 0:03.42 12.8% 91+667k 0+17io 0pf+0w 3.4 seconds (that's freebsd 3.0-current options: nfsv3,intr,tcp,rw,bg) time dd if=www2_otherlocal.tar.gz of=/dev/null bs=128k 219+1 records in 219+1 records out 0.010u 1.550s 0:16.00 9.7% 0+0k 0+0io 84pf+0w an even 16 seconds (linux) [Redhat 5.1] (dunno the opts) this is on the same 100mbit segment. i'm using NFS over TCP and linux is using UDP (i think) both to the same Solaris 5.6 box. the FreeBSD box is my tuning (just the mount opts listed above), the redhat box has also been tuned by a linux user. i heard that linux now has kernel NFS but i doubt the stability and performance since it's so new. (still smirking) and they wonder why i run freebsd on my workstation... *sigh* if someone has a mount option for the linux box they'd like to share _please_ respond privately, i'd appreciate it as well as those on the list.
