I'm trying to run some IOzone benchmarking on a new system to get a
feel for baseline performance.
Unfortunately, the system has a lot of memory (144GB), but I have some
time so am approaching my runs as follows:
Throughput:
iozone -m -t 8 -T -r 128k -o -s 36G -R -b bigfile.xls
IOPS:
iozone -O -i 0 -i 1 -i 2 -e -+n -r 128K -s 288G > iops.txt
Not sure what I gain/lose by using threads or not.
Am I off on this?
System is a 240x2TB (7200RPM) system in 20 Dell MD1200 JBODs. 16 vdevs of 15
disks each -- RAIDZ3. NexentaStor 3.1.2.
