Last time I used DBM::Deep, it was everything, but NOT fast. It's easy to use and powerful. It does persistent multi-level structures in pure Perl. It has a responsive author. It's great software. But it's seriously not very fast. Make sure you do some proper benchmarking before deciding to use it all out. If the benchmarks show it's okay for your use case, then I highly recommend it.
