Hello,

I have read the - very interesting - performance comparison

I'd like to ask if someone did benchmark LMDB (and/or the others)
against http://www.garret.ru/fastdb.html

FastDB is an in-memory ACID database that works via shadow paging, and
without a transaction log.

OK, like LMDB it uses shadow root pages. I think the similarity ends there.
It is a relational database with an ASCII query language, while LMDB is strictly a key/value store. That automatically means for simple get/put operations LMDB will be orders of magnitude faster (just as it is so much faster than SQLite3 and SQLite4).

I Not being so young, these considerations remind me of the same arguments that there was about  hierarchical  DBMS and the relational one. I do not mean that there are not still real, but just to tell that we are talking about topic  20 years old. Isn't it ?
