in reply to System V shared Memory Perl Module (more of a C question than Perl) aka Efficient SQL result caching

Hang on there, you just picked the wrong module. Cache::FileCache is much faster than the shared memory version, and other are still faster than it.

Take a look at these: IPC::MM, BerkeleyDB, Cache::Mmap, MLDBM::Sync (with SDBM_File).
