Kevin's reference is actually to a Sybase manual page; very interesting. This refers to the idea of subdividing the lock into may partitions. That's already been discussed, but that is the next step beyond where we are right now with a single cache but a much improved cache algorithm. That technique is an algorithmic improvement rather than a hardware specific improvment, which is what is required in the case we are dealing with here. Cool reference. The idea of named caches is more familiar to me. Tuning for that is just too hard and massively inflexible, so I don't think its the way anybody really wants to go, but I hold the door open for anybody travelling that way. > >>> Bruce Momjian <pgman@candle.pha.pa.us> >>> > > How do other databases deal with this?

What do other OSS projects do about this is more likely an answerable question.
