A quick question that probably has a long and winded answer?
On a single box portal instance, which is better? 2 x 512 Mb nodes or 1 x 1024 Mb node.
I assume the basic answer is partly based on memory in the machine, number of potential users etc etc ?
The memory is probably the easy one since if you have lots of memory you need more instances to be able to use it. But for an arbitrary group of users is one better than the other from a general usability perspective?
