Yeah, I know about the performance overhead of logging. We have some embedded devices that do minimal logging on flash storage and if you log that you missed a timing on the critical path, it causes you to miss another timing, and this leads to a cascade that bricks the entire device because the CPU only does logging and can't even receive any commands.
