IO测试

• 测试随机读取 fio -filename=/tmp/test_randread -direct=1 -iodepth 1 -thread -rw=randread -ioengine=psync -bs=16k -size=30G -numjobs=10 -runtime=60 -group_reporting -name=mytest
• 测试随机写入 fio -filename=/tmp/test_randread -direct=1 -iodepth 1 -thread -rw=randread -ioengine=psync -bs=16k -size=30G -numjobs=10 -runtime=600 -group_reporting -name=mytest
• 顺序读 fio -filename=/tmp/test_randread -direct=1 -iodepth 1 -thread -rw=read -ioengine=psync -bs=16k -size=30G -numjobs=10 -runtime=60 -group_reporting -name=mytest
• 顺序写 fio -filename=/data/test_randread -direct=1 -iodepth 1 -thread -rw=write -ioengine=psync -bs=16k -size=30G -numjobs=10 -runtime=600 -group_reporting -name=mytest
• 混合随机读写 fio -filename=/tmp/test_randread -direct=1 -iodepth 1 -thread -rw=randrw -rwmixread=70 -ioengine=psync -bs=16k -size=30G -numjobs=10 -runtime=600 -group_reporting -name=mytest -ioscheduler=noop
