Not applicable, since ovdb is older than the entire SQLite project.

Just an anecdotal data point: ovdb was much faster than buffindexed
at expiration when I switched overview methods for my private server
back in 2010.

Now that I can build ovdb again, I'll definitely run benchmark tests
comparing ovdb and ovsqlite.
