Ah! Who was the Apple engineer who told us during the last WWDC that
performance should be important design consideration for every
application from the early design phase?
You are may be reading a little to much into John's statement, I doubt
he think optimization shouldn't be a concern from the get go...
From the get go of a project performance should be a major concern and
design factor however you should never make most optimizations without
measuring the affects and necessity of those changes. In others words
don't make them assuming they are needed or help. You should set
performance metrics, threshold, requirements, etc. and continuously
measure against them while developing. It will be an iterative process.
That is what they did with Safari (they tried not to allow performance
regressions as the project progress).
In general one should favor simpler code as long as the performance of
it is sufficient.
