If I have a fixed amount of money to spend as a general rule is it better to buy one processor and lots of memory or two processors and less memory for a system which is transactional based (in this case it's handling reservations). I realise the answer will be a generalised one but all the performance bits I've read seem to talk about adjusting memory allocation. The client has received the general advice from their hardware supplier that 2 Xeon processors and less memory is better but for postgresql I'm thinking they might be better off with a single processor and loads of memory. The OS is Red Hat Linux.
How long is a piece of string I guess but all comments welcome!
