Hi,
I'd like to draw your attention to the case of slow (comparing to .shp)
writing times of GPKG.
See https://github.com/r-spatial/sf/issues/470 for the details and some
benchmarks.
Jakub,
A quick search in the code shows that sf doesn't use
OGRLayer::StartTransaction() / CommitTransaction() to surround calls to
CreateFeature(). By default, SQLite auto-commits each INSERT, which is slow.
Doing insertion by batches within a single (or several) transactions helps a
lot.
