There are few tuning settings available in LMDB. The vast majority of the real-world performance you will receive comes down to understanding your data write patterns, read patterns, optimal layout, transaction coordination (eg avoiding unnecessary transactions) and using the correct create-time flags (for example on Env
and Dbi
) to support this. These are not specific to LmdbJava but the underlying LMDB library. The wiki offers a lot of higher-level guidance on these topics and you can also ask on LMDB forums if unsure.
