Fastest cpu secs Racket versus Python 3 Always look at the source code. If the fastest programs are hand-written vector instructions, does the host language matter? You might be more interested in the less optimised programs — more cpu seconds, less gz source code. fannkuch-redux source mem gz cpu Racket #2 66,616 908 111.70 Racket #3 68,148 1101 120.34 Racket 66,312 649 143.11 Python 3 #6 7,432 385 1,279.15 Python 3 #4 45,420 950 1,336.72 n-body source mem gz cpu Racket #2 68,496 1689 14.09 Racket 68,936 1496 40.83 Python 3 7,756 1196 575.02 Python 3 #2 8,244 1242 592.71 spectral-norm source mem gz cpu Racket #3 65,100 627 14.71 Racket #2 65,336 532 14.99 Racket 66,852 446 29.47 Python 3 #6 9,332 328 436.79 Python 3 #8 48,336 407 472.82 Python 3 #7 48,400 417 494.32 mandelbrot source mem gz cpu Racket #3 65,448 802 34.63 Racket #4 103,948 801 41.19 Racket 66,768 517 49.23 Racket #2 65,576 585 51.16 Python 3 #7 46,192 688 706.10 Python 3 #5 Failed Python 3 #2 Timed Out pidigits source mem gz cpu Racket #2 67,012 1136 1.02 Python 3 #3 11,968 567 1.13 Python 3 #4 8,668 342 4.06 Racket 71,068 453 12.25 Python 3 #2 Bad Output regex-redux source mem gz cpu Python 3 #2 111,680 1403 2.66 Python 3 458,264 512 17.86 Racket 2,074,452 541 21.84 Racket #2 2,003,760 729 22.58 fasta source mem gz cpu Racket #3 66,908 1280 7.99 Racket 66,768 1066 18.91 Python 3 #2 8,184 1121 60.26 Python 3 #3 8,112 1003 60.50 Python 3 8,040 817 70.54 Python 3 #5 837,684 1947 71.74 k-nucleotide source mem gz cpu Racket #4 988,500 885 63.58 Python 3 #3 252,668 1967 172.53 Racket 2,614,596 547 199.02 Python 3 351,092 607 240.16 Python 3 #8 473,988 655 242.16 reverse-complement source mem gz cpu Racket #2 687,976 1030 8.74 Python 3 #2 1,786,488 434 9.38 Python 3 1,979,276 479 9.63 Python 3 #6 1,005,184 814 10.64 Python 3 #4 4,001,684 335 12.31 Racket 2,575,076 553 39.70 binary-trees source mem gz cpu Racket #3 299,864 473 6.42 Racket #4 545,328 853 8.90 Racket #2 308,092 416 8.95 Racket 435,536 476 15.25 Python 3 #2 270,872 338 148.09 Python 3 #5 273,284 660 172.44 Python 3 #4 456,220 472 176.37 Python 3 282,996 589 178.66 Python 3 #3 669,832 1238 230.73 Racket Racket v8.5 [cs].
