Some benchmark results for various combinations of hardware, Gforth version, and Gforth configuration. Unless specified otherwise, the default configurations were used. You can measure your combination with `make bench'. You can find a table comparing Gforth with six interpretive Forth systems in the manual (Section Performance), and a comparison with more systems in http://www.complang.tuwien.ac.at/papers/ertl&maierhofer95.ps.gz. All times are given in seconds of user time. siev bubble matrix fib machine and configuration 1.52 2.09 2.56 2.59 Athlon 600; gcc-2.95.2; gforth-0.4.9 -DFORCE_REG; ELF 2.39 3.38 4.13 4.18 Celeron 450 (Mendocino); gcc-2.7.2.3 -DFORCE-REG -DDIRECT-THREADED; gforth-0.3.0; ELF 1.97 2.84 3.21 3.24 Celeron 450 (Mendocino); gcc-2.95; gforth-0.4.9 -DFORCE_REG; ELF 6.88 7.43 5.80 8.15 AMD K6-2 300MHz 1M PB cache 100MHz; gcc-2.7.2.3 -DFORCE-REG; gforth-0.4.0; ELF 7.61 8.14 6.50 9.13 AMD K6-2 300MHz 1M PB cache 100MHz; gcc-2.95.1 -DFORCE-REG -DUSE_NO_TOS; gforth-0.4.9; ELF 6.77 7.21 5.39 7.85 AMD K6-2 300MHz 1M PB cache 100MHz; gcc-2.95.1 -DFORCE-REG -DUSE_TOS; gforth-0.4.9; ELF 5.91 6.89 5.99 7.63 Pentium-MMX 200MHz 512K PB cache; gcc-2.95 -DFORCE-REG -DUSE_TOS; gforth-0.4.9; ELF 6.68 7.95 6.41 7.99 Pentium-MMX 200MHz 512K PB cache; egcs-1.1b -DFORCE-REG -DUSE_TOS; gforth-0.4.9; ELF 7.09 7.70 7.20 8.74 Pentium-MMX 200MHz 512K PB cache; gcc-2.95 -DFORCE-REG; gforth-0.4.9; ELF 7.23 7.81 7.22 8.47 Pentium-MMX 200MHz 512K PB cache; gcc-2.7.2.3 -DFORCE-REG; gforth-0.3.0; ELF 7.36 8.16 7.73 9.04 Pentium-MMX 200MHz 512K PB cache; egcs-1.1b -DFORCE-REG; gforth-0.4.0; ELF 10.91 11.94 11.24 13.13 Pentium 133MHz 256K PB cache; gcc-2.6.3 -DFORCE_REG; gforth-0.1beta; a.out 11.16 11.86 10.64 12.53 Pentium 133MHz 512K PB cache; gcc-2.7.2p -DFORCE_REG, gforth-0.3.0; ELF 12.62 13.56 11.04 14.97 AMD K6 166MHz 512K PB cache; gcc-2.7.2p -DFORCE_REG, gforth-0.3.0; ELF 11.81 14.39 13.61 15.07 IBM/Cyrix-6x86 133MHz (P166+) 512K PB cache; gcc-2.7.2.1 -DFORCE_REG -DDIRECT_THREADED; gforth-0.3.0; ELF 12.08 11.90 11.06 12.09 Cyrix-6x86MX 166MHz (PR200) 512K PB Cache; gcc-2.7.2.1 -DFORCE_REG -DDIRECT_THREADED; gforth-0.3.0; ELF 29.89 35.42 26.96 34.59 i486 66MHz 256K cache; gcc-2.6.3 -DFORCE_REG -DDIRECT_THREADED; gforth-0.1beta; a.out 26.19 29.92 23.80 30.18 i486 66MHz 256K cache; gcc-2.95.1 -DFORCE_REG; gforth-0.4.9; ELF 39.50 45.91 36.73 44.90 i486 50MHz 256K cache; gcc-2.7.0 -DFORCE_REG -DDIRECT_THREADED; gforth-0.1beta 42.82 46.74 38.69 48.30 i486 50MHz 256K cache; gcc-2.7.0 -DFORCE_REG; gforth-0.1beta 2.14 3.11 3.20 3.96 21264 (Compaq XP 1000) 500MHz 4M cache; egcs-1.0.3+gas; gforth-0.4.0 2.03 2.91 3.45 4.39 21264 (Compaq XP 1000) 500MHz 4M cache; gcc-2.95.1 -mcpu=21164a -DFORCE_REG; gforth-0.4.9 3.09 3.24 2.39 3.42 21164A (Alpha,164LX) 600MHz 2M cache; gcc-2.7.2.1+gas; gforth-0.3.0 2.74 2.95 2.20 3.45 21164a (Alpha,164LX) 600MHz 2M cache; gcc-2.95.1 -mcpu=21164a -DFORCE_REG; gforth-0.4.9 3.7 3.8 2.8 4.1 21164A (Alpha,PC164) 500MHz 2M cache; gcc-2.7.2.1+as (Digital Unix); gforth-0.3.0 7.0 7.6 6.2 7.7 21064A (Alpha,Cabriolet) 300MHz 2M cache; gcc-2.7.2; gforth-0.2.0 7.49 7.85 6.21 8.07 R4400 250 Mhz 2Mb cache; gcc-2.7.2.2 7.45 7.98 5.82 9.44 R10000 (SGI PowerChallenge XL) 195MHz 2M cache; egcs-1.1.2 -DFORCE_REG; gforth-0.4.9 17.3 19.0 14.1 18.3 R4000 (DecStation 5000/150) 100MHz 1M cache; gcc-2.4.5; gforth-0.1beta 50.9 56.8 42.4 52.0 R3000 (DecStation 5000/200) 25MHz 64K+64K cache; gcc-2.5.8 -DFORCE_REG; gforth-0.1beta 7.8 8.6 7.0 10.3 UltraSparc-II 248MHz; Solaris.5.5.1; gcc-2.7.1; gforth-0.3.0 28.5 31.1 26.3 33.3 SuperSparc (Sparcstation 10) 40MHz; Solaris.5.5.1; gcc-2.7.1; gforth-0.3.0 59.5 65.8 69.5 61.9 FJMB86903 (SPARC ELC) 33MHz; gcc-2.5.8; gforth-0.1beta 84.34 91.49 76.16 88.83 L64801 25MHz (SPARC IPC) 64K WT cache; gcc-2.4.5; gforth-0.1beta 11.6 12.1 10.8 15.6 PA8000 (HP C160) 160MHz 64M RAM; gcc-2.7.2; gforth-0.3.0 30.0 34.1 20.5 33.0 PA-RISC 1.1 (HP 720) 50MHz 64K cache; gcc-2.6.3 -DDIRECT_THREADED; gforth-0.1beta 3.36 4.06 2.39 4.33 PPC750 (PowerMac 7500, G3-upgrade) 308MHz; Linux; egcs-1.02; gforth 0.4.0-19990312 5.68 6.53 4.25 7.47 PPC604e (PowerMac) 200MHz; Linux; gcc-2.7.2.1; gforth-0.4.0-19990312 6.81 7.53 5.10 8.12 PPC604e (PowerMac) 200MHz; Linux; gcc-2.7.2.1; gforth-0.4.0 8.25 10.09 6.45 10.34 PPC604e (PowerMac) 200MHz; Linux; gcc-2.7.2.1; gforth-0.3.0 (indirect threaded) 14.05 16.96 11.14 17.51 PPC604 (PowerMac) 132MHz 256K L2 cache; MkLinux 2.1; gcc-2.7.2.1; gforth-0.3.0 7.42 8.81 5.96 8.61 PPC603 (Amiga + BlizzardPPC) 160Mhz; gcc-2.95.2 -DDIRECT_THREADED; gforth-0.4.9-19990617 16.29 10.38 7.58 10.5 PPC603 (Amiga + BlizzardPPC) 160Mhz; gcc-2.95.2 -DINDIRECT_THREADED; gforth-0.4.9-19990617
