Fastest cpu secs Julia 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 Julia #2 211,980 1067 29.46 Julia #3 204,120 886 31.21 Julia 181,932 434 44.01 Python 3 #6 7,432 385 1,279.15 Python 3 #4 45,420 950 1,336.72 n-body source mem gz cpu Julia #8 225,844 1111 4.49 Julia #4 202,592 1155 5.95 Julia #3 207,868 1541 7.05 Julia #2 268,512 1078 24.49 Python 3 7,756 1196 575.02 Python 3 #2 8,244 1242 592.71 spectral-norm source mem gz cpu Julia #4 188,696 429 3.72 Julia #2 200,160 370 5.12 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 Julia #7 236,644 619 5.08 Julia #8 236,112 624 5.24 Julia #6 253,220 562 5.87 Julia #5 272,904 571 5.94 Julia #4 257,796 574 7.69 Julia #3 273,584 579 7.77 Julia 210,712 373 27.06 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 Julia #3 179,360 506 1.24 Julia #2 190,376 674 1.34 Julia 265,496 275 2.15 Python 3 #4 8,668 342 4.06 Python 3 #2 Bad Output regex-redux source mem gz cpu Python 3 #2 111,680 1403 2.66 Julia #5 403,608 759 3.12 Julia #4 410,768 766 3.19 Julia #3 502,440 622 3.68 Julia 380,060 408 3.88 Python 3 458,264 512 17.86 fasta source mem gz cpu Julia #8 198,752 1082 1.40 Julia #5 219,876 950 2.89 Julia #4 203,872 1049 3.12 Julia #7 459,380 1182 4.92 Julia #6 407,228 1203 5.54 Julia #3 237,412 896 27.78 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 Julia #8 366,728 951 11.31 Julia #7 370,872 1368 18.12 Python 3 #3 252,668 1967 172.53 Julia 1,962,152 695 196.54 Python 3 351,092 607 240.16 Python 3 #8 473,988 655 242.16 reverse-complement source mem gz cpu Julia #8 683,748 522 1.71 Julia #9 681,000 449 1.95 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 Julia #2 1,742,028 460 32.14 binary-trees source mem gz cpu Julia #2 600,804 423 37.16 Julia #4 495,284 372 47.16 Julia #3 608,728 634 48.85 Julia #5 665,480 390 79.14 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 Julia julia version 1.7.2 Python 3 Python 3.10.4 all Julia programs & measurements all Python 3 programs & measurements
