Answer 1

"Boilerplate" has nothing to do with performance: it just means standard code that is required to define an application or work with some framework. It's code that is likely to be identical in every application.

A "hot spot", on the other hand, means a part of the code that is executed many times and therefore its performance matters a lot to the overall application performance. Usually a hot spot is identified by actual profiling: it's not a hot spot if it's executed many times but is so trivial that its impact on performance is minimal.
