GML is the default format, but a WFS server can deliver other formats with
better performance.
For example, GeoServer currently has a community module
<https://docs.geoserver.org/latest/en/user/community/flatgeobuf/installing.html>
that adds a FlatGeoBuf <https://github.com/flatgeobuf/flatgeobuf> WFS
output format.
If QGIS could use it for reading*, then at least part of the performance
issue could be solved.

Cheers
Andrea

*: this likely requires some development, but GDAL/OGR has support for
FlatGeoBuf <https://gdal.org/drivers/vector/flatgeobuf.html>, so hopefully,
not
too much extra effort.
