Performance Tips

Reading and decoding the data stored in baseband files can be somewhat slow, especially if the analysis itself is simple. So far, code development has focussed more on correctness than on performance, but a few things can help.

Note

If you have other tips on performance or contributions that help improve it, please raise an issue or make a pull request!

Minimize Verification

Once you know a file does not have missing frames or is otherwise slighly corrupted, you can speed up reading by turning off verification of headers, by passing in verify=False when opening the stream reader.

Parallel Processing

Like python file readers in general, baseband’s stream readers cannot be used in parallel threads. They can, however, be sent from process to process using pickle (or copied using copy.deepcopy).
