Never believe synthetic benchmarks. They are quite useless for real
world applications.

Compare real world applications that do same jobs.

I'm not familiar with it. But as it is dynamically typed language
it will be always significantly slower then any statically typed one.

What kind of transactions? What kind of schema, etc.

I've read plenty good benchmarks for BDB that where... not so realistic
in real world.

Same as before. Compare real world applications.

P.S.: If k=0 this is quite not interesting as it does not provide D of
ACID.

In any case... DB choice is choice specific for every singe case.
