I have also seen (unspecified) system libraries worsen considerably over time - 'faster over the course of OS releases' is not as sunny as I once believed. Believing system libraries will get faster is dangerous.

You have filed bugs against said regressions? Performance regressions are serious business. Send me the bug #s offlist. I would like to track them.


Spending loads of engineering time re-inventing the wheel is folly. It often isn't faster, is generally buggier, and consumes a ton of time that could be better used actually shipping something.

Not to be meant as an insult to anyone's engineering skills on this list. Simply that if you were to focus as much time on optimizing and debugging an algorithm found in a system library as the engineers who wrote and now maintain said library, you are unlikely going to have enough time left over to ship your product.
