I'm looking for better ways to convert between #QGIS VectorLayers and #GeoPandas GeoDataFrames. #pyogrio and #arrow look promising (reduces run time by 50%) but when I try to wrap it in a Processing script, it gets tricky ...

Test using Arrow for QGIS to geopandas conversion

In an attempt to speed-up (and make the conversion more robust, eg regarding datetime/timezone conversion and null values (https://codeberg.org/movingpandas/trajectools/issues/93)), we can try to use Arrow. Since QGIS currently does not support exporting a layer to Arrow, here is a test workaroun...
