I previously came out with a version that converts a BF program directly into a module, which has received some optimization contributions from Matthew Flatt. Got some pretty good results.
Execute bench.b in cpu time: 1542 ms, (2.2s include compile time). And mandel.b in cpu time: 3851 ms, (7s include compile time). But you have to manually "export PLT_CS_COMPILE_LIMIT=100000" environment variable in order to get compiled and executed properly. https://gist.github.com/sleepnova/92d7b2a7f077e7de76da4ce31f60335e philngu...@gmail.com <philnguyen0...@gmail.com> 於 2021年3月1日 週一 下午3:39寫道： > There’s this benchmark on BF interpreter where the Racket > <https://github.com/kostya/benchmarks/blob/master/brainfuck/bf.rkt> and Chez > Scheme <https://github.com/kostya/benchmarks/blob/master/brainfuck/bf.ss> > implementations are very similar, but Chez Scheme is much faster than > Racket 8.0 at interpreting bench.b > <https://github.com/kostya/benchmarks#benchb> (3s vs 8s) and mandel.b > <https://github.com/kostya/benchmarks#mandelb> (40s vs 136s). > > There’s the “Racket (Syntax Object) > <https://github.com/kostya/benchmarks/blob/master/brainfuck/bf-syntax.rkt#L75>” > variant that directly parses BF’s syntax into Racket syntax object, which > is faster (3.7s for bench, 82s for mandel), but still significantly behind > Chez Scheme’s naive interpreter. > > Profiling doesn’t give very illuminating results, saying most of the cost > is from interpreting BF’s loop instruction. > > Given that Racket is on Chez, could this benchmark reveal some low hanging > fruit for improving Racket’s performance? > > -- > You received this message because you are subscribed to the Google Groups > "Racket Users" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to racket-users+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/racket-users/83b2819d-8295-4769-944d-fa0c155976dan%40googlegroups.com > <https://groups.google.com/d/msgid/racket-users/83b2819d-8295-4769-944d-fa0c155976dan%40googlegroups.com?utm_medium=email&utm_source=footer> > . > -- - sleepnova 呼叫小黃創辦人 & CEO -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
