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 8.18 464,444 478 24.76 87% 72% 72% 71% Java 8.32 953,620 835 28.37 95% 87% 81% 77% spectral-norm source secs mem gz busy cpu load Erlang HiPE 20.84 32,656 747 68.21 85% 84% 79% 79% Java 4.22 36,948 950 16.43 98% 97% 98% 96% pidigits source secs mem gz busy cpu load Erlang HiPE 16.28 29,064 562 20.61 18% 99% 2% 8% Java 3.07 39,320 938 3.31 2% 5% 3% 98% regex-redux source secs mem gz busy cpu load Erlang HiPE 56.34 1,994,236 1048 85.86 54% 27% 32% 40% Java 10.31 644,560 740 31.47 72% 72% 92% 70% fannkuch-redux source secs mem gz busy cpu load Erlang HiPE 85.39 24,184 1038 338.26 97% 100% 100% 100% Java 14.33 34,888 1282 56.56 99% 98% 99% 98% n-body source secs mem gz busy cpu load Erlang HiPE 194.05 24,108 1399 196.23 100% 0% 0% 1% Java 21.93 35,408 1429 22.44 1% 0% 100% 1% reverse-complement source secs mem gz busy cpu load Erlang HiPE 41.91 2,708,764 1302 116.88 73% 80% 62% 64% Java 3.16 712,368 2183 7.08 65% 47% 42% 70% k-nucleotide source secs mem gz busy cpu load Erlang HiPE 138.53 752,144 937 392.68 65% 65% 61% 92% Java 9.33 447,976 1812 29.36 73% 83% 82% 77% mandelbrot source secs mem gz busy cpu load Erlang HiPE 110.22 52,080 792 440.54 100% 100% 100% 100% Java 6.83 79,108 796 26.86 97% 99% 99% 99% fasta source secs mem gz busy cpu load Erlang HiPE 48.54 23,740 1164 53.00 61% 16% 1% 30% Java 2.22 45,172 2473 5.99 61% 50% 98% 60% Erlang HiPE Erlang/OTP 22 [erts-10.5] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe] Java openjdk 13 2019-09-17 OpenJDK Runtime Environment (build 13+33) OpenJDK 64-Bit Server VM (build 13+33, mixed mode, sharing) all Erlang HiPE programs & measurements all Java programs & measurements
