Speeding up the performance

Hi Tobias,

I'm a beginner to C++, been learning it for the last 10~ days. I have previously written some code in Python to split very large BLF files into smaller files (a need existing among colleagues at work). It is performing very slow for files larger than 500 MB.

That is why I decided to explore other options to see if I can speed up the performance. I've now experimented with your library, and it seems that there is no difference in speed (the python library is based upon your C++ library). I'm wondering if it is possible to speed up the performance when I split a BLF-file, is there anything I can do to minimize the memory used to read and write each CAN-message into smaller BLF-files?

Best regards Robin.
