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 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 13.61 15.05 14.07 17.33 IBM/Cyrix-6x86 133MHz (P166+) 512K PB cache; gcc-2.7.2.1 -DFORCE_REG; gforth-0.2.1; 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 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 7.0 7.6 6.2 7.7 21064A (Alpha) 300MHz 2M cache; gcc-2.7.2; gforth-0.2.0 17.3 19.0 14.1 18.3 R4000 100MHz 1M cache; gcc-2.4.5; gforth-0.1beta 50.9 56.8 42.4 52.0 R3000 25MHz 64K+64K cache; gcc-2.5.8 -DFORCE_REG; gforth-0.1beta 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 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
