Just out of curiosity, is the problem just the number of connections to 
the database? If that is what the problem is, are you using 
mysql_connect() or mysql_pconnect()? The pconnect method creates a pool 
of database connections and reuses that pool. It requires using php as a 
module in apache. It might require a bit of tweaking to use properly but 
might be useful.

Other than that, I would say try memcache. Or writing your own caching 
layer if you are particularly masochistic. (I'll keep comments about php 
being masochistic to myself).

There are a few thoughts about what you can do.
