Most of the shared memory modules are much slower than Berkeley DB. The fastest option around is IPC::MM, but data you store in that does not persist if you restart the server which is a problem for some. BerkeleyDB (the new one, not DB_File) is also very fast, and other options like Cache::Mmap and Cache::FileCache are much faster than anything based on IPC::Sharelite and the like. I have charts and numbers in my TPC presentation, which I will be putting up soon. - Perrin
