.. _benchmarks:

Intro
-----

The benchmarks were done using two test files (available here https://github.com/danielhrisca/asammdf/issues/14) (for mdf version 3 and 4) of around 170MB. 
The files contain 183 data groups and a total of 36424 channels.

*asamdf 2.8.0* was compared against *mdfreader 2.7.2* (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

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 )
   

x64 Python results
------------------
Benchmark environment

* 3.6.1 (v3.6.1:69c0db5, Mar 21 2017, 18:41:36) [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

* full =  asammdf MDF object created with memory=full (everything loaded into RAM)
* low =  asammdf MDF object created with memory=low (raw channel data not loaded into RAM, but metadata loaded to RAM)
* minimum =  asammdf MDF object created with memory=full (lowest possible RAM usage)
* compress = mdfreader mdf object created with compression=blosc
* compression bcolz 6 = mdfreader mdf object created with compression=6
* noDataLoading = mdfreader mdf object read with noDataLoading=True

Files used for benchmark:

* 183 groups
* 36424 channels
