Thank you, we would like to help more, but C is not our favorite language.
Kind regards

Comment(by mmetz):
Some comments on the patch:
The patch makes sense to me and is indeed a substantial speed improval.
However, partitions were confused with categories. The patch was written
in C++ style, but the module is a C module. I made further changes to the
patch: the attribute table of current vector is modified instead of
creating a new vector, giving a further speed-up. The vector is opened
without topology, that makes it easier for larger point clouds. Updating
the database uses db_[begin|commit]_transaction(), giving a further speed-
up.
Thanks for your contribution!
