Nice stuff but I am not sure that having shared memory per slot scales when having a lot of entries, but that makes sure that one process/thread won't overwrite another one slot.
It scales very nicely. We run with max clients set between 16k-32k with no issues. Our item sizes range from 64-264 bytes. at 264 bytes and 24k max clients, it requires about 6.5 MB of shared memory and we usually have 8-12 "slotmems" of varying sizes, so we use about 32-64 MB of shared memory for all the "slotmems."
It is very fast as there is no locking necessary as each slot is only every written to by a single writer (it's "tied" to a connection id).
