Julia versus C gcc 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% C gcc 1.75 2,608 452 1.80 67% 0% 2% 33% fannkuch-redux source secs mem gz busy cpu load Julia 10.62 190,312 886 39.95 93% 92% 99% 93% C gcc 8.73 696 910 34.46 100% 95% 100% 100% n-body source secs mem gz busy cpu load Julia 9.57 240,732 1112 10.20 2% 70% 32% 3% C gcc 7.30 8 1391 7.41 0% 1% 100% 0% spectral-norm source secs mem gz busy cpu load Julia 2.79 179,764 521 9.07 75% 75% 76% 99% C gcc 1.98 988 569 7.89 99% 99% 100% 99% k-nucleotide source secs mem gz busy cpu load Julia 7.55 344,020 945 17.36 61% 41% 50% 78% C gcc 4.84 130,192 1506 16.00 98% 83% 63% 87% reverse-complement source secs mem gz busy cpu load Julia 3.03 671,492 522 3.54 5% 8% 6% 98% C gcc 1.92 551,900 820 2.58 20% 99% 14% 1% mandelbrot source secs mem gz busy cpu load Julia 2.64 224,160 619 9.34 86% 98% 85% 85% C gcc 1.64 27,024 1135 6.53 99% 99% 100% 100% fasta source secs mem gz busy cpu load Julia 2.93 363,468 1182 8.91 74% 79% 78% 73% C gcc 1.46 2,948 2268 5.84 100% 99% 100% 99% regex-redux source secs mem gz busy cpu load Julia 3.04 439,520 766 5.17 4% 62% 5% 98% C gcc 1.42 152,192 1397 3.40 100% 48% 48% 44% binary-trees source secs mem gz busy cpu load Julia 20.21 601,980 372 66.53 90% 78% 82% 79% C gcc 3.59 168,896 809 11.86 77% 74% 98% 82% Julia julia version 1.4.0 C gcc gcc (Ubuntu 9.3.0-10ubuntu2) 9.3.0 all Julia programs & measurements all C gcc programs & measurements
