Create Large Files to Test Throughput Rates

There may be occasions when you want to test the throughput rates for a large file. In our case, we wanted to use files of certain sizes to accomplish these tests. I suggested using the mkfile command to create the predetermined file sizes.

Here's what was done.

Create a 1MB file
# mkfile 1m 1MB

Create a 5MB file
# mkfile 5m 5MB

Create 10MB file
# mkfile 10m 10MB

Create 100MB file
# mkfile 100m 100MB

Create 1GB file
# mkfile 1000m 1GB

Extra: Use Z Shell brace expansion to create multiple test files
