Autovacuum makes the database a little larger (by a few percent) and it makes DELETE operations a little slower (by about 20%, IIRC). More details are forthcoming.

[sqlite] How efficiently will SQLite work as a queue?
I am contemplating using SQLite as a message queueing mechanism, and was wondering whether this would be efficient. In particular, I will be adding new records to a table, while another process removes those records when it is ready to handle that "message". My question relates to possible fragmentation that may occur within the database file as records are deleted. Will SQLite efficiently reclaim the space used by the deleted records? I am looking at the PRAGMA auto_vacuum command. How efficient is this (as far as time is concerned. I am not concerned about space)?
