Performance

crbcc performance measured against standard GNU-R compiler. Speedup compiling a function measured by compiling it 10 times, result is the mean value. Average compiler speedup of a package is the average of speedups on compiling all of its functions.

Measured on Intel Core i5-8400 CPU @ 2.80GHz, RAM 16GB (inside Docker on Windows 11).
