Client is a Digital Prioris HX6000, P6-200/512cache, 32MB RAM, SMC
100Mbit ethernet.
Server is a Network Appliance F540, 100GB disk, 8MB NVRAM, 128MB cache,
100MBit ethernet.
I tried both TCP and UDP mounts, version 3 and version 2 NFS. The
best performance was UDP version 3, for what that's worth.
# iozone 500
Writing the 500 Megabyte file, 'iozone.tmp'...86.304688 seconds
Reading the file...90.789062 seconds
IOZONE performance measurements:
6074849 bytes/second for writing the file
5774792 bytes/second for reading the file
using 64k block sizes resulted in about a 4% perf increase, however, it
dropped CPU utilization on the Netapp from 100% to about 65%.
Here's some bonnie numbers as well. Note that for bonnie, the best combo
was UDP version 2, rather than version 3. Wish I knew why.
In a nutshell, almost as fast as the fastest single spindles.
