Fastest cpu secs Python 3 versus Node js 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 Node js #5 85,336 1313 44.58 Python 3 #6 7,432 385 1,279.15 Python 3 #4 45,420 950 1,336.72 n-body source mem gz cpu Node js #6 41,056 1268 8.43 Python 3 7,756 1196 575.02 Python 3 #2 8,244 1242 592.71 spectral-norm source mem gz cpu Node js #7 41,524 414 5.38 Node js 41,668 319 5.45 Node js #6 90,932 999 6.20 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 Node js #3 118,180 1122 16.00 Node js #2 48,484 416 28.21 Node js 43,580 373 65.26 Python 3 #7 46,192 688 706.10 Python 3 #5 Failed Python 3 #2 Timed Out pidigits source mem gz cpu Python 3 #3 11,968 567 1.13 Node js #4 45,096 481 1.14 Python 3 #4 8,668 342 4.06 Node js #2 72,556 397 13.11 Node js #3 72,536 424 13.22 Python 3 #2 Bad Output regex-redux source mem gz cpu Python 3 #2 111,680 1403 2.66 Node js #3 1,045,556 668 5.97 Node js #4 985,940 463 6.24 Python 3 458,264 512 17.86 fasta source mem gz cpu Node js #5 101,844 2047 6.38 Node js 50,304 809 37.60 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 Node js #3 419,748 1812 43.70 Node js #2 72,156 935 112.88 Node js 621,752 1008 115.69 Python 3 #3 252,668 1967 172.53 Python 3 351,092 607 240.16 Python 3 #8 473,988 655 242.16 reverse-complement source mem gz cpu Node js #7 1,556,168 1480 4.97 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 Node js #2 727,572 1221 16.87 binary-trees source mem gz cpu Node js #6 1,322,340 744 27.83 Node js 1,173,028 711 36.72 Node js #7 1,107,220 451 40.72 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 Python 3 Python 3.10.4 Node js v18.1.0 all Python 3 programs & measurements all Node js programs & measurements
