JVM Heap Size - Min & Max the same or different?

Hi
I am using WAS 6.0 for B7334 on Windows 2003,
What are peoples opinions on having the heap min and max the same e.g 512mb as opposed to min 512mb, max 1024mb.
In the past I've set them to be different to allow the heap to grow but has anyone seen any performance issues with doing that? I've seen documents outlining both.
Thanks!

Oracle does recommend to have them set to the same for optimum performance. I usually set them to 2-4GB depending on user load.
