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 4.12 460,684 478 12.01 77% 66% 75% 73% Java 2.49 2,490,296 835 7.88 92% 75% 78% 72% fannkuch-redux source secs mem gz busy cpu load Erlang HiPE 59.89 24,880 1038 234.88 99% 95% 99% 99% Java 9.94 34,188 1282 39.21 99% 98% 99% 97% spectral-norm source secs mem gz busy cpu load Erlang HiPE 11.17 36,596 747 44.05 99% 99% 98% 98% Java 1.66 38,280 950 6.36 97% 95% 96% 96% regex-redux source secs mem gz busy cpu load Erlang HiPE 41.91 3,377,136 1048 61.09 16% 45% 22% 63% Java 5.58 656,192 929 17.84 83% 83% 80% 74% pidigits source secs mem gz busy cpu load Erlang HiPE 7.89 28,324 562 8.51 2% 3% 96% 6% Java 0.94 35,604 764 0.99 1% 4% 3% 97% reverse-complement source secs mem gz busy cpu load Erlang HiPE 25.49 2,842,416 1302 68.58 70% 59% 71% 68% Java 1.53 720,672 2183 3.57 52% 63% 59% 59% k-nucleotide source secs mem gz busy cpu load Erlang HiPE 84.67 830,416 937 238.48 68% 75% 61% 78% Java 4.88 409,508 1812 15.86 75% 88% 86% 77% mandelbrot source secs mem gz busy cpu load Erlang HiPE 85.08 55,736 806 340.11 100% 100% 100% 100% Java 4.15 70,040 796 16.34 98% 98% 99% 98% n-body source secs mem gz busy cpu load Erlang HiPE 140.37 23,972 1399 143.03 1% 99% 1% 1% Java 6.76 35,156 1489 6.83 1% 0% 100% 1% fasta source secs mem gz busy cpu load Erlang HiPE 56.64 24,760 1039 71.26 6% 100% 8% 12% Java 1.28 44,172 2473 4.17 83% 78% 88% 76% Erlang HiPE Erlang/OTP 23 [erts-11.0] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe] Java openjdk 15 2020-09-15 OpenJDK Runtime Environment (build 15+36-1562) OpenJDK 64-Bit Server VM (build 15+36-1562, mixed mode, sharing) all Erlang HiPE programs & measurements all Java programs & measurements
