Useful numbers. It looks as if File::Cache is the best approach if you
need anything beyond the SDBM size limit. Maybe some fine-tuning of that
module could bring it more in line with SDBM performance.
If you have the RAM to spare - and I guess you do, if you're considering
things like RAM disks - you could try IPC::MM too. I think it will be
faster than the other IPC modules because it's a Perl API to a shared hash
written in C.
