Program: File name as it's seen in the source code repository. ASM: Total number of Assembly instructions seen in the compiled .asm file; not every compiler provides this information though. Cycles: How many times the Fibonacci number has been calculated. Time: How many seconds it took to execute all calculations. SPC: How many seconds per each calculation. Ticks: How many total CPU ticks it took to execute all calculations, according to perf. TPC: How many ticks per a single calculation. GHz: TPC divided by SPC and divided by one billion; this is approximately how fast is the CPU; this metric for all programs is expected to have almost the same values, otherwise something is wrong with the method.
Maximum optimization is enabled in all compilers.
