Isn't it more of a "cost vs benefit" issue? If there is a significant enough benefit, then the cost is justified? Otherwise, there would never be anyone going to new releases. Plus, there are patches that are applied all the time to fix problems - and sometimes fix performance problems.

I think the question is whether any performance bottlenecks can be addressed via patches, and how much performance can be gained that way - and how much performance could be gained by redesigning/recompiling an application. Would you agree with this?
