Lisp SBCL versus Java fastest performance Always look at the source code. If the fastest programs are hand-written vector instructions, does the host language matter? You might be more interested in the less optimised programs — more seconds, less gz source code. fannkuch-redux source secs mem gz cpu secs Lisp SBCL #5 30.39 49,920 689 30.38 Lisp SBCL #3 37.50 32,768 833 37.50 Lisp SBCL #4 10.13 33,152 1531 39.42 Java #3 40.76 42,844 1264 40.83 Java 10.98 42,812 1289 43.36 Java #2 44.03 40,916 520 44.09 Lisp SBCL #2 49.10 19,668 525 49.09 n-body source secs mem gz cpu secs Java #5 6.78 41,384 1435 6.82 Java #4 6.87 41,188 1495 6.91 Java #2 7.42 41,308 1430 7.46 Java #3 7.47 41,256 1436 7.51 Lisp SBCL #2 7.81 19,816 1408 7.81 Java 7.85 41,512 1437 7.89 Lisp SBCL 9.26 19,816 1373 9.26 spectral-norm source secs mem gz cpu secs Lisp SBCL #6 5.32 20,736 512 5.32 Lisp SBCL 5.32 19,816 639 5.32 Lisp SBCL #3 1.45 19,688 893 5.45 Lisp SBCL #8 1.45 19,688 799 5.46 Lisp SBCL #7 1.44 19,816 769 5.46 Lisp SBCL #2 1.46 19,816 920 5.46 Java #3 1.66 42,924 762 6.21 Java 7.07 42,268 521 7.13 Java #2 2.40 42,164 956 9.25 mandelbrot source secs mem gz cpu secs Java #4 4.45 104,488 667 16.20 Java #2 4.13 83,152 802 16.22 Lisp SBCL 4.75 50,944 2478 16.49 Lisp SBCL #4 4.18 42,752 2453 16.60 Java #6 4.28 83,056 808 16.84 Java 25.70 41,388 671 25.76 Lisp SBCL #3 9.70 50,048 900 25.95 Java #3 7.86 83,424 910 30.96 pidigits source secs mem gz cpu secs Java #3 0.93 40,860 770 0.96 Java #2 1.34 44,524 944 1.42 Lisp SBCL #4 3.37 429,312 495 3.37 Lisp SBCL #3 3.38 434,560 499 3.38 Lisp SBCL #2 6.01 429,816 655 6.01 Java 7.61 486,236 807 8.69 regex-redux source secs mem gz cpu secs Java 8.38 666,804 875 16.42 Java #3 5.17 671,372 935 17.04 Java #6 5.57 1,234,928 746 17.17 Lisp SBCL #4 14.08 994,024 1977 29.33 fasta source secs mem gz cpu secs Java #4 3.15 42,784 1528 3.26 Java #6 1.18 48,408 2549 3.71 Java #5 1.24 48,752 2478 3.81 Lisp SBCL #6 4.42 19,668 1763 4.42 Java #2 4.35 47,184 1259 4.50 Lisp SBCL #3 5.82 19,796 1592 5.82 Lisp SBCL 9.24 21,760 1430 9.24 Lisp SBCL #2 9.25 19,668 1628 9.25 k-nucleotide source secs mem gz cpu secs Java 5.01 368,104 1821 16.33 Lisp SBCL #4 16.70 156,288 2292 16.70 Lisp SBCL #5 16.83 156,416 2323 16.83 Java #6 7.18 365,592 1614 25.01 Java #3 7.30 365,348 1642 25.39 Java #4 34.43 195,584 1887 34.79 Java #5 16.05 219,872 2225 38.17 Lisp SBCL #6 10.97 541,312 2485 40.13 Lisp SBCL 12.76 550,784 2431 41.85 Lisp SBCL #3 51.99 558,208 1297 51.99 Lisp SBCL #2 53.23 558,208 1291 53.23 reverse-complement source secs mem gz cpu secs Java #6 3.33 2,031,460 760 3.96 Java #5 4.73 1,096,344 1115 4.86 Lisp SBCL 5.35 1,517,184 911 5.34 Java #4 5.57 1,889,928 656 5.68 Java #7 23.06 1,036,296 1654 6.31 Lisp SBCL #2 Failed Java #3 Bad Output Java #8 Bad Output binary-trees source secs mem gz cpu secs Java #4 4.50 2,081,744 846 5.22 Java #3 4.80 2,076,860 546 5.59 Java #6 4.84 2,097,072 535 5.60 Java #2 4.93 2,067,656 558 5.67 Lisp SBCL #3 3.30 476,572 938 7.64 Java #7 2.57 1,728,452 841 8.00 Lisp SBCL 9.68 461,412 595 9.68 Lisp SBCL SBCL 2.4.2 Java java 22 2024-03-19 Java HotSpot(TM) 64-Bit Server VM (build 22+36-2370, mixed mode, sharing) all Lisp SBCL programs & measurements all Java programs & measurements
