Julia versus Lisp SBCL fastest programs Always look at the source code. These are only the fastest programs. Look at the other programs. They may seem more-like a fair comparison to you. pidigits source secs mem gz busy cpu load Julia 2.06 169,012 506 2.55 99% 6% 13% 6% Lisp SBCL 12.37 131,624 493 12.55 0% 0% 37% 63% reverse-complement source secs mem gz busy cpu load Julia 3.03 671,492 522 3.54 5% 8% 6% 98% Lisp SBCL 11.42 1,390,812 904 11.59 1% 1% 49% 51% n-body source secs mem gz busy cpu load Julia 9.57 240,732 1112 10.20 2% 70% 32% 3% Lisp SBCL 26.19 17,660 1403 26.35 91% 9% 0% 0% mandelbrot source secs mem gz busy cpu load Julia 2.64 224,160 619 9.34 86% 98% 85% 85% Lisp SBCL 6.66 46,768 2447 26.53 99% 99% 100% 99% fasta source secs mem gz busy cpu load Julia 2.93 363,468 1182 8.91 74% 79% 78% 73% Lisp SBCL 7.09 17,724 1757 7.18 1% 1% 88% 12% k-nucleotide source secs mem gz busy cpu load Julia 7.55 344,020 945 17.36 61% 41% 50% 78% Lisp SBCL 16.10 538,172 2479 57.76 98% 88% 86% 86% spectral-norm source secs mem gz busy cpu load Julia 2.79 179,764 521 9.07 75% 75% 76% 99% Lisp SBCL 4.00 19,808 890 15.78 98% 99% 99% 99% fannkuch-redux source secs mem gz busy cpu load Julia 10.62 190,312 886 39.95 93% 92% 99% 93% Lisp SBCL 12.06 33,044 1527 47.21 95% 99% 98% 99% binary-trees source secs mem gz busy cpu load Julia 20.21 601,980 372 66.53 90% 78% 82% 79% Lisp SBCL 11.41 321,692 932 24.35 53% 73% 42% 45% regex-redux source secs mem gz busy cpu load Julia 3.04 439,520 766 5.17 4% 62% 5% 98% Lisp SBCL Failed Julia julia version 1.4.0 Lisp SBCL SBCL 2.0.4 all Julia programs & measurements all Lisp SBCL programs & measurements
