Benchmarks¶

Test setup¶

The benchmarks were done using two test files (available here) (for mdf version 3 and 4) of around 170MB. The files contain 183 data groups and a total of 36424 channels.

asamdf 8.8.0 was compared against mdfreader 4.2.

For each category two aspect were noted: elapsed time and peak RAM usage.

Dependencies¶

You will need the following packages to be able to run the benchmark script

psutil
mdfreader

Usage¶

Extract the test files from the archive, or provide a folder that contains the files “test.mdf” and “test.mf4”. Run the module bench.py ( see –help option for available options )
