I would suggest that you ditch Apache::Speedlimit, since it uses
IPC::Shareable which is known to have some performance issues and is
giving you grief about memory size. Do a quick search in the list
archives for Randal's Stonehenge::Throttle code. It's fairly easy to
adapt it to use cookies and to count hits within a time window rather
than CPU. It uses files, and doesn't have to lock them. Quite fast under
Linux, and even works over NFS if you need a clustered solution.
