  This is a design question.... We are building a new RAC, we currently have a 4 node RAC and we are upgrading the hardware and software and are wondering whether to go with a 3 node RAC or a 4 node RAC. I've heard rumors that 3node RAC perform better (we have no 4-way current gc waits, but there are a lot of 3-way current waits)...

   So, what I'm looking for is links or experiences regarding 3-way and 4-way RACs.

Thanks in advance
