Hello,

I want to know what is the best practice for the database settings for import forums?

I have a big phpbb db with 100,000 topics and mabout 8000 users.

Especially
Rows Limit
100 rows to process at a time
Keep this low if you experience out-of-memory issues.

Delay Time
1 second(s) delay between each group of rows
Keep this high to prevent too-many-connection issues.

And what does Convert users mean?
Attempt to import user accounts from previous forums. Non-bbPress passwords cannot be automatically converted. They will be converted as each user logs in.
