    Pretty sure the C performance would have been trivially matched by C# were it to be ported there.

    While not XML (which does not see much love from the community to surprise of HN), gigabytes per second of parsing throughput are reached for CSV without sacrificing UX: https://github.com/nietras/Sep?tab=readme-ov-file#packageass...

    Your issue is that you're using the default (old) binding to GDAL, based on Fiona [0].

    You need to use pyogrio [1], its vectorized counterpart, instead. Make sure you use `engine="pyogrio"` when calling `to_file` [2]. Fiona does a loop in Python, while pyogrio is exclusively compiled. So pyogrio is usually about 10-15x faster than fiona. Soon, in pyogrio version 0.8, it will be another ~2-4x faster than pyogrio is now [3].
