> A single-threaded algorithm will likely smoke a locking multi-threaded algorithm when run on a single-core Do you claim the single-threaded program will speed-up on single-core? Do you claim the multi-threaded program will slow-down on single-core? We can look in the Internet Archive and see neither of those things happened — Free Pascal mandelbrot #4 program [multi threaded] 68.18 elapsed secs, 68.15 cpu secs [single core] 17.07 elapsed secs, 68.14 cpu secs [quad core] Free Pascal mandelbrot #3 program [single threaded] 75.47 elapsed secs, 75.43 cpu secs [single core] 75.47 elapsed secs, 75.44 cpu secs [quad core] https://web.archive.org/web/20150221165617/http://benchmarksgame.alioth.debian.org/u64/performance.php?test=mandelbrot https://web.archive.org/web/20150221165617/http://benchmarks... https://web.archive.org/web/20150221172620/http://benchmarksgame.alioth.debian.org/u64q/performance.php?test=mandelbrot https://web.archive.org/web/20150221172620/http://benchmarks...
