This is writing to a raid0 fs on a FreeBSD/i386 server using an nfsv3 mount, udp, 8k read/write size: % dd if=/dev/zero of=bigfile bs=1024k count=5000 5000+0 records in 5000+0 records out 5242880000 bytes transferred in 471.673794 secs (11115479 bytes/sec) This is writing to a software raid5 fs on a Solaris/x86 (2.8) server using an nfsv3 mount, udp, 8k read/write size: % dd if=/dev/zero of=bigfile bs=1024k count=5000 5000+0 records in 5000+0 records out 5242880000 bytes transferred in 1165.859965 secs (4497007 bytes/sec) Maybe you should look at "lmdd" ? Maybe it is either buggy, or it was compiled a long, long time ago? (btw, this is a virgin 4.2 install, with none of my nfs opts in it).
