I want to start using iozone to benchmark a usb stick I have.
I want a very simple test to measure 4k random writes.
I tried following the manual to use relevant parameters, but I keep getting a weird error on most runs. Some runs will pass ok, though with extraordinary values such as 200000kb/s.
Most runs will simply fail as such
sudo iozone -i 2 -R -l 1 -u 1 -r 4k -s 10m -F ~/f3 | tee -a /tmp/iozone_results.txt ... Min process = 1 Max process = 1 Throughput test with 1 process Each process writes a 10240 Kbyte file in 4 Kbyte records ~/f3: No such file or directory
Can anyone please provide some advice on what am I doing wrong? I obviously have permissions, and just in case chmod 777 to my home dir and the relevant file system mount point.
