What is your usecase if I may ask?
Only fio/iozone now, maybe you can give me better test sugguestion :)
seq read
# dd if=/dev/zero of=test bs=4k count=524288
#fio --filename=test -iodepth=64 -ioengine=libaio --direct=1 --rw=read
--bs=1m --size=2g --numjobs=4 --runtime=10 --group_reporting
--name=test-read
seq write
# fio -filename=test -iodepth=64 -ioengine=libaio -direct=1 -rw=write
-bs=1m -size=2g -numjobs=4 -runtime=20 -group_reporting -name=test-write
random read
#fio -filename=test -iodepth=64 -ioengine=libaio -direct=1 -rw=randread
-bs=4k -size=2G -numjobs=64 -runtime=20 -group_reporting
-name=test-rand-read
random write
#fio -filename=test -iodepth=64 -ioengine=libaio -direct=1 -rw=randwrite
-bs=4k -size=2G -numjobs=64 -runtime=20 -group_reporting
-name=test-rand-write
iozone 1 thread
# ./iozone -s 10g -r 1m -i 0 -i 1 -f /mnt/test-volume/test -Rb
/tmp/test_iozone_1.xls
iozone 2 multi-threads
# ./iozone -s 10g -r 1m -i 0 -i 1 -f /mnt/test-volume/test -t 8 -Rb
/tmp/test_iozone_2.xls
Re-declare,
For fio, i compare "bw" and "iops" fileds.
For iozone, i compare "write" "rewrite" "read" "re-read" fileds.
