FIO Performance Testing

This chapter introduces using FIO to test Curvine's performance.

Test Environment

The test machine configuration is as follows:

• Worker machine type: i3en.24xlarge, Operating system: RedHat 9
• Client machine type: c5n.18xlarge, Operating system: RedHat 9
• FIO version: 3.5

Test Tools

Using FIO to test Curvine's performance. The test cases are as follows:

# 256KB sequential read
fio -iodepth=1 -rw=read \
-ioengine=libaio -bs=256k -group_reporting -size=100gb \
-filename=/curvine-fuse/0  -name=read_test --readonly \
-direct=1 --runtime=60 -numjobs={job_num}

# 256K random read
fio -iodepth=1 -rw=randread \
-ioengine=libaio -bs=256k -group_reporting -size=100gb \
-filename=/curvine-fuse/0  -name=read_test --readonly \
-direct=1 --runtime=60 -numjobs={job_num}

# 4k random read
fio -iodepth=1 -rw=randread \
-ioengine=libaio -bs=4k -group_reporting -size=100gb \
-filename=/curvine-fuse/0  -name=read_test --readonly \
-direct=1 --runtime=60 -numjobs={job_num}
