> When we have a base with, say, 10000 entries, deleting one of them takes forever. A short
analysis conducted by Stefan Seelmann shown that the problem lies in the way we handle indexes
(log for one entry) :
> JdbmStore: lookup in 0ms
> JdbmStore: drop alias indices in 0ms
> JdbmStore: drop ndn index in 78ms
> JdbmStore: drop updn index in 34ms
> JdbmStore: drop onelevel indices in 426ms
> JdbmStore: drop sublevel index in 525ms
> JdbmStore: drop parent onelevel index in 0ms
> JdbmStore: drop existence index in 3ms
> JdbmStore: master delete in 0ms
> JdbmStore: sync in 7ms
