Erlang HiPE versus Java 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. binary-trees source secs mem gz busy cpu load Erlang HiPE 8.33 468,264 478 25.17 76% 83% 71% 72% Java 8.28 948,040 835 28.20 80% 84% 87% 90% spectral-norm source secs mem gz busy cpu load Erlang HiPE 16.73 34,356 747 64.19 97% 95% 95% 97% Java 4.15 36,428 950 16.26 98% 100% 98% 97% fannkuch-redux source secs mem gz busy cpu load Erlang HiPE 84.89 24,188 1038 337.93 99% 100% 99% 100% Java 16.12 33,168 1282 63.71 100% 98% 99% 98% regex-redux source secs mem gz busy cpu load Erlang HiPE 60.01 2,136,672 1048 101.58 39% 41% 36% 53% Java 10.27 635,500 740 29.42 74% 81% 55% 76% n-body source secs mem gz busy cpu load Erlang HiPE 191.97 24,504 1399 204.49 37% 33% 26% 11% Java 21.85 34,112 1489 22.16 1% 0% 0% 100% pidigits source secs mem gz busy cpu load Erlang HiPE 16.33 27,624 562 17.76 9% 4% 3% 93% Java 1.83 34,848 764 1.95 99% 1% 4% 2% reverse-complement source secs mem gz busy cpu load Erlang HiPE 41.88 2,600,884 1302 115.39 74% 77% 62% 62% Java 3.27 714,144 2183 7.54 47% 60% 66% 58% k-nucleotide source secs mem gz busy cpu load Erlang HiPE 144.25 757,756 937 407.46 91% 66% 62% 63% Java 9.14 403,576 1812 29.10 87% 72% 74% 86% mandelbrot source secs mem gz busy cpu load Erlang HiPE 109.96 51,676 792 439.44 100% 100% 100% 100% Java 6.84 76,008 796 26.90 99% 98% 98% 98% fasta source secs mem gz busy cpu load Erlang HiPE 48.18 24,632 1164 52.97 6% 51% 49% 4% Java 2.22 43,096 2473 6.10 67% 83% 45% 80% Erlang HiPE Erlang/OTP 22 [erts-10.7] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe] Java openjdk 14 2020-03-17 OpenJDK Runtime Environment (build 14+36-1461) OpenJDK 64-Bit Server VM (build 14+36-1461, mixed mode, sharing) all Erlang HiPE programs & measurements all Java programs & measurements
