I noticed it visually, but other then using something like iozone21, not sure what is useful for coming up with a benchmark … I've just ran something like dd if=/dev/zero of=bla bs=1000000 count=1000 on the nfsmount on the client. mount 10.10.91.226:/zones/userdata/shares/nfs/test-export /home/mpd-test/nfs-test dd if=/dev/zero of=bla bs=1000000 count=1000 1000+0 records in 1000+0 records out 1000000000 bytes transferred in 27.826971 secs (35936358 bytes/sec) mount -o nfsv3,rsize=131072,wsize=131072 10.10.91.226:/zones/userdata/shares/nfs/test-export /home/mpd-test/nfs-test dd if=/dev/zero of=bla bs=1000000 count=1000 1000+0 records in 1000+0 records out 1000000000 bytes transferred in 78.594951 secs (12723464 bytes/sec) mount -o nfsv3,rsize=65536,wsize=65536 10.10.91.226:/zones/userdata/shares/nfs/test-export /home/mpd-test/nfs-test dd if=/dev/zero of=bla bs=1000000 count=1000 1000+0 records in 1000+0 records out 1000000000 bytes transferred in 68.243100 secs (14653496 bytes/sec) mount -o nfsv3,rsize=32768,wsize=32768 10.10.91.226:/zones/userdata/shares/nfs/test-export /home/mpd-test/nfs-test dd if=/dev/zero of=bla bs=1000000 count=1000 1000+0 records in 1000+0 records out 1000000000 bytes transferred in 13.326178 secs (75040270 bytes/sec) mount -o nfsv3,rsize=16384,wsize=16384 10.10.91.226:/zones/userdata/shares/nfs/test-export /home/mpd-test/nfs-test dd if=/dev/zero of=bla bs=1000000 count=1000 1000+0 records in 1000+0 records out 1000000000 bytes transferred in 11.965145 secs (83576086 bytes/sec) mount -o nfsv3,rsize=8182,wsize=8192 10.10.91.226:/zones/userdata/shares/nfs/test-export /home/mpd-test/nfs-test dd if=/dev/zero of=bla bs=1000000 count=1000 1000+0 records in 1000+0 records out 1000000000 bytes transferred in 11.861178 secs (84308657 bytes/sec)
