Intro
-----

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

*asamdf 2.5.3* was compared against *mdfreader 0.2.5* (latest versions from PyPI). 
*mdfreader* seems to be the most used Python package to handle MDF files, and it also supports both version 3 and 4 of the standard.

The three benchmark cathegories are file open, file save and extracting the data for all channels inside the file(36424 calls).
For each cathegory 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

x64 Python results
------------------
The test environment used for 64 bit tests had:

* 3.6.2 (v3.6.2:5fd33b5, Jul  8 2017, 04:57:36) [MSC v.1900 64 bit (AMD64)]
* Windows-10-10.0.14393-SP0
* Intel64 Family 6 Model 94 Stepping 3, GenuineIntel
* 16GB installed RAM

Notations used in the results:

* nodata = asammdf MDF object created with load_measured_data=False (raw channel data not loaded into RAM)

Files used for benchmark:

* 183 groups
* 36424 channels
