After spending several hours trying to improve the whole code responsible for adding / writing media items retrieved from a media provider into Kodi's database I realized that I only had to adjust the SQL transaction handling to improve the performance by a factor of up to 50. I only tested this on SQLite (so no idea what the performance with MySQL is) and the improvements vary depending on whether the SQLite database is located on a HDD or SDD but either way the performance improvement should be significant. On my dev computer importing 60 movies to an HDD took ~80s and on an SSD it took ~9s. With the improvements this went down to ~1.4s. Now when importing a large library the main time is spent on retrieving the media items from the media provider - adding the retrieved items to the database is very fast.

And last but not least these new test builds are based on Kodi v19 (final).
