Blogbench is a benchmark, which simmulates a normal fileserver workload. It uses multible threads to perform random read, writes and rewrites.
This is the most basic way of running blogbench:
blogbench -d </path/to/directory>
Running blogbench like this :
blogbench -d testdir
will result in an output like this:
Frequency = 10 secs Scratch dir = [testdir] Spawning 3 writers... Spawning 1 rewriters... Spawning 5 commenters... Spawning 100 readers... Benchmarking for 30 iterations. The test will run during 5 minutes.
