some good benchmarks comparing MySQL vs file-mapped containers: http://lightwave.visula.org/persist/bench.html and I'm sure boost::shmem::allocator is similar. Performance is very good. We could devise a benchmark and I'll implement in RML + Persist/Shmem, you implement in SQLlite and we'll see the difference.
The one killer limitation of shmem (that I'm pretty sure Ion is working hard to remove) is that the shared memory region cannot be grown once it has been created. This is where your memory-mapped "persist" library has a leg up. -- Caleb Epstein caleb dot epstein at gmail dot com
