Postmark is a benchmark designed to simulate the behavior of mail servers. Postmark consists of three phases. In the first phase a pool of files are created. In the next phase four types of transactions are executed: files are created, deleted, read, and appended to. In the last phase, all files in the pool are deleted.
The PostMark can be run with phoronix-test-suite. Refer to this blog on how to install phoronix-test-suite.
The first run
When you have first run of PostMark, it will have the additional dependent packages installed automatically.
These are the default configuration options for when running the Phoronix Test Suite in a batch mode (i.e. running phoronix-test-suite batch-benchmark universe). Running in a batch mode is designed to be as autonomous as possible, except forwhere you'd like any end-user interaction. Save test results when in batch mode (Y/n): y Open the web browser automatically when in batch mode (y/N): n Auto upload the results to OpenBenchmarking.org (Y/n): n Prompt for test identifier (Y/n): n Prompt for test description (Y/n): n Prompt for saved results file-name (Y/n): n Run all test options (Y/n): n Batch settings saved.
After setting up batch mode, you can run the test as below.

Compare multiple runs
In the case you need to tweak some settings and run it again, and you want to compare the results for multipe runs. You can use the phoronix-test-suite merge-results command.
