There are several important reason to upgrade to 3.1. Speed is NOT one of them. Stability IS!
When it comes to "stability" Kickstart 3.0 and 3.1 are same.
Some games like dynAMIte run little faster on Kickstart 3.1 because they use WCP()(? IIRC) on the 3.1 ROM but Kickstart 3.1 is not faster than 3.0.
It is like upgrading from 2.04 to 2.1. Very little new, old same thing.
