NFS Speed Test: Quick and Dirty
Here is a quick and dirty way to test your NFS transfer speed. What I did was to use the command “dd” to create a dummy file on the network share mounted with NFS. This will work when mounting a network share with Samba as well.
First, mount your network share if it is not already mounted.
Now, lets create the file, here is the syntax of the dd command to create the file. I will fill the file with NULL characters.
dd if=/dev/zero of=zerofile.test bs=1k count=5000000
Explanation of above command:
if = input file
of = output file
bs = block size
count = file size in kb
The output will show you the size of the file created, how long it took, and how fast in MB/s that it “transferred” the file across the network.
Example output:
5120000000 bytes (5.1 GB) copied, 134.357 s, 38.1 MB/s
