I was about to recommend looking at Cache::SharedMemoryCache. And then I read it. It says to use a filesystem cache because the speed difference is trivial. Which tells me that simply bumping up your buffers for your database may solve your speed problems. Instead of throwing memory at a shared memory cache, throw that memory at the database, and see if that helps.
