This topic describes how to use the fio tool to measure the throughput and input/output operations per second (IOPS) of Apsara File Storage NAS.
Performance testing in Linux
- The sunrpc_slot parameter must be set to a proper value. For more information, see Why is the performance of an NFS client poor on Linux?.
- The maximum throughput of a file system cannot exceed the bandwidth of an Elastic Compute Service (ECS) instance. If the bandwidth of the ECS instance is 1 Gbit/s, the throughput of the file system can reach a maximum of 125 MB/s.
- The fio tool is pre-installed on your ECS instance. If the fio tool is unavailable,
run the following command to install the tool:
- If CentOS, Red Hat Enterprise Linux (RHEL), or Aliyun Linux is running on the ECS
instance, run the following command to install the tool:
sudo yum install fio
- If Ubuntu or Debian is running on the ECS instance, run the following commands to
install the tool:
sudo apt-get update
sudo apt-get install fio
- If CentOS, Red Hat Enterprise Linux (RHEL), or Aliyun Linux is running on the ECS
instance, run the following command to install the tool:
- Random read IOPS
fio -numjobs=1 -iodepth=128 -direct=1 -ioengine=libaio -sync=1 -rw=randread -bs=4K -size=1G -time_based -runtime=60 -name=Fio -directory=/mnt
Estimated value: 14,000
- Random write IOPS
fio -numjobs=1 -iodepth=128 -direct=1 -ioengine=libaio -sync=1 -rw=randwrite -bs=4K -size=1G -time_based -runtime=60 -name=Fio -directory=/mnt
Estimated value: 10,000
- Random read throughput
fio -numjobs=1 -iodepth=128 -direct=1 -ioengine=libaio -sync=1 -rw=randread -bs=1M -size=1G -time_based -runtime=60 -name=Fio -directory=/mnt
- Estimated value for NAS Capacity: 150 MB/s
- Estimated value for NAS Performance: 300 MB/s
- Estimated value for NAS Capacity: 150 MB/s
- Random write throughput
fio -numjobs=1 -iodepth=128 -direct=1 -ioengine=libaio -sync=1 -rw=randwrite -bs=1M -size=1G -time_based -runtime=60 -name=Fio -directory=/mnt
- Estimated value for NAS Capacity: 150 MB/s
- Estimated value for NAS Performance: 300 MB/s
- Estimated value for NAS Capacity: 150 MB/s
Performance testing in Windows
- The requests to access a file system from a Windows server are processed in serial. Therefore, multiple files are used in the following performance tests.
You can download and install a Microsoft Installer (MSI) package of the fio tool on a Windows server. To download the MSI package, visit the fio official website.
In this example, a NAS file system is mounted on Disk Z and the fio tool is installed in the C:\Program Files\fio\fio.exe directory. You can run the following commands to conduct performance tests.
- Random read IOPS
"c:\Program Files\fio\fio.exe" -name=Fio -numjobs=2 -iodepth=128 -direct=1 -ioengine=windowsaio -sync=1 -rw=randread -bs=4K -size=1G -time_based -runtime=60 -group_reporting -thread -directory=Z\:\
Estimated value: 14,000
- Random write IOPS
