[elephant-devel] Elephant backend performance characteristics

[Alex Mizrahi]

 LPP> BDB is the fastest backend currently available. Postmodern
 LPP> is about half as fast

a little clarification -- it is not like there is a constant slowness 
factor.
PostgreSQL storage itself is pretty fast , and probably in some aspects
it is even better than BDB storage.

but there is pretty high communication overhead associated with each
operation, so often postmodern is a lot slower than bdb. also storage
was modelled after BDB API, and thus it is pretty hard to implement
same semantics on top of SQL database, so some stuff is implemented
in very inefficient manner.
