The NFS protocol, which is short for Network File System, was invented by Sun Microsystems in 1984. Although the protocol was developed long ago, it’s still widely used today because of its simplicity and scalability. In this tutorial, I’ll show you how to test NFS performance on a Linux system using dd command.
Step 1 – Install NFS server and NFS client on both machines.
To ensure that the NFS server and client are installed on both machines, you need to follow the steps given below:
- Install NFS server on both machines.
- Install NFS client on both machines.
- Make sure that your network is in same subnet.
Step 2 – Create a test file on the NFS server.
You can now create a test file on the NFS server.
Use dd command to create a test file. Use the following dd command to create a test file:
dd if=/dev/zero of=test.file bs=64k count=1000
Step 3 – Mount the share point from the NFS client machine.
Mount the share point from the NFS client machine.
To mount a share point, use the mount command with options as shown below.
# mount -t : :
Step 4 – Test block device speed on the client side.
Now that you’ve checked the server side, it’s time to test the speed of your NFS share on the client side.
- Mount an NFS share point by using its name or IP address:
- [sudo] mount :/ /mnt/data -o nolock,vers=4.1
- If you want to check for any errors in mounting your NFS share point, use -v parameter after mounting it:
- [sudo] mount -v :/ /mnt/data
Step 5 – Test NFS performance using dd command in Linux.
To test NFS performance, you can use the dd command. Follow these steps:
Step 1 – First, check the status of your file system using df command. It will show you all mounted partitions and their mountpoint and available space on each partition. If you want to know more about df command then read our article How To Use The “df” Command In Linux?
Step 2 – Start copying large files from NFS server to local disk using dd for instance:
dd if=/mnt/nfs/myfile of=/dev/sdb bs=4096 ibs=4096 count=50 conv=noerror,sync
dd command is one of my favorite tools to test I/O performance of storage devices, hard drives, and networks.
One of my favorite tools to test I/O performance of storage devices, hard drives, and networks is dd command.
dd command is a powerful tool to test I/O performance of storage devices, hard drives, and networks.
dd command can be used in many ways to benchmark performance of different drives, partitions, file systems or any other block device.
dd is one of my favorite tools to test I/O performance of storage devices, hard drives, and networks. It can be used in a lot of scenarios, like testing file copy speed or network bandwidth. DD command has many options that let users control several settings related to performance, such as number of input/output operations per second (IOPS) and block size; however, these settings may vary depending on the type of device being tested (e.g., hard drive vs network). In this article we will show how to use dd command for testing NFS performance on Linux systems with some examples!
