Performance Improvements for FreeBSD kernel debugging

We previously explored FreeBSD userspace coredumps. Backtrace’s debugging platform supports FreeBSD kernel coredumps too, and their traces share many features. They are constructed somewhat differently, and in the process of adding support for them, we found a way to improve performance for automated programs accessing them. Read on to learn how information is extracted from a FreeBSD kernel core, and how we improved performance for this mechanism. Generating kernel core files A kernel core is typically only generated in exceptional circumstances.
