Detailed Description

The console's measurements of the panel itself: PSRAM (pseudo-static RAM) speed at start-up, the frame times, and every task's stack and the internal heap at their lowest.

Built with the option RCBENCH_PERF_LOG, ON by default (firmware/panel/CMakeLists.txt). Built without it,

idf.py -D RCBENCH_PERF_LOG=OFF build

every call below is an empty inline function, panel_perf.c is not compiled, and the panel prints none of these lines and runs none of their code. docs/Performance.md names the lines and the tables they fill.
