What are suggested settings? I'm only running a very simple database  approx 3000 transactions each day (500 users normally) Total size of the database is now approx 100mb.

This will pose a big problem. My motherboard only supports up to 768Mb memory If I'm correct. (have to find that out though)

True this is normally the desired situation, but I'm running into money problems here . ;]. I'm just on a small (personal) budget with this one. My company provides me the nesessary Oracle licenses but I've got to install my own servers.

True It will help a bit, but with further tuning down the database to more normal memory usages will increase performance If I'm correct?
