Full circle back to the original topic...
IPC::MM is implemented in C and offers an actual hash interface backed by a
BTree in shared memory.  IPC::ShareLite only works for individual scalars.

It wouldn't surprise me if a file system approach was faster than either of
these on Linux, because of the agressive caching.
