Hi,
I've been doing some testing with Bonnie++ trying to figure out if it would
make sense to additionally tune network throughput (the storage being a
possible showstopper).
I do read tests with "hdparm -tT" and this seems to give me a single and clear
results for a particular device.
However for writes I turn to the output section of Bonnie, which results into
three values (per-character, block and rewrites). Which value do I have to
take into account? Which one needs to be compared to the results of a network
throughput test with netperf?
My example:
scsi2:/install/bonnie/bonnie++-1.03e # bonnie++ -d /mnt/test/ -s 4016 -u root
Using uid:0, gid:0.
