I haven't confirmed this, but I've read several reports that both
MySQL and mSQL both have performance/scalability problems with large
databases.  You may want to investigate this area.

I've only read references to it.  I suspect that all the real
discussion occurred on Marcus Ranum's Wizard list, which was in many
ways the equivalent of MUD-Dev 10 years ago (and sadly seems to be
last as far as archives are concerned).

My current implementation uses a linear TDBM descendant.  In moving
towards more of a persistent store model I've gone towards Persist++
and Texas munged into my prior TDBM-like model (and have ended up with
a right load of bollocks, if a set of interesting proof cases).
