lmdb's memory and disk footprint is small. My Æ-DIR development VMs are
really small (~200 MB RAM) and there are various web components running
on the providers.

I even tested this stuff with Raspberry PI model 1.
And it did not consume too much resources.
(Of course SD cards have really slow disk I/O.)

AFAICS there is only one case where back-mdb is significantly slower
than back-hdb: ITS#8875. But this is actively worked on.

So stop spreading FUD about lmdb. If you provide real-world evidence
that back-mdb consumes more resources than back-hdb then present
seriously worked out test results.
