Talk:Brainfuck speed test

Please try mine too

I've got one for you: https://codeberg.org/splot-dev/splotbf#installation, thank you. It should work on Windows... although tell me if it doesn't. —User:Splot-dev

OK, I'll use the source code next time I retest (soon). --None1 (Nope.) 06:45, 13 August 2026 (UTC)

I'm sorry but your interpreter cannot interpret dbfi when not debugging (it runs into an infinite loop), so I'm not adding it this time. --None1 (Nope.) 15:04, 14 August 2026 (UTC)

Oh! what was happening was that you didn't wait for dbfi to start accepting input—hence the infinite loop! Here, I made the benchmark for you.

Try this please (read the bolded notes): https://esolangs.org/wiki/User:Splot-dev/splotbf/benchmark

Also, please update splotbf to v1.3.1: pip install splotbf --upgrade

—User:Splot-dev

OK. I still wonder why your interpreter needs a long time to load. --None1 (Nope.) 06:53, 17 August 2026 (UTC)

Your benchmark program raises AttributeError: module 'pexpect' has no attribute 'spawn'. I had both packages upgraded before running. --None1 (Nope.) 08:18, 17 August 2026 (UTC)

I fixed it, but your program ran for more than 5min, so I can't add it. --None1 (Nope.) 09:08, 17 August 2026 (UTC)

This is very confusing: I'm getting 'Time: 4.08881729200948 seconds.'. I believe that pexpect is not supported for Windows, and the I/O format of PopenSpawn, which you might've used to fix it, is not supported by splotbf.

Well, I'm not gonna try at this anymore.

Hello, could you please try my bf interpreter and bf-to-rust transpiler?

https://github.com/pro465/bf-rs

Thanks! --Pro465 (talk) 15:18, 5 September 2023 (UTC)

Ok, I'll try it later. --None1 (talk) 13:36, 6 September 2023 (UTC)

I've tested your interpreter and it takes about 3 secs to run. I modified your interpreter so that works under Windows. Unfortunately, I can't test your compiler because I can't modify it so that it works under Windows probably because I'm not good enough at Rust, please modify it yourself so that I can run it correctly on my computer. --None1 (talk) 14:44, 6 September 2023 (UTC)

thanks and sorry! I fixed it now and tested it under W11, so could you please try again?

(I'll fix the interpreter too -- it probably could also be a lot faster now that I'm more experienced in rust). btw you are running cargo b --release, right? --Pro465 (talk) 17:31, 6 September 2023 (UTC)

I've tested compiler, it took about 0.8 seconds. (Note: Unlike what you expected, I run rustc main.rs) --None1 (talk) 09:26, 7 September 2023 (UTC)

thanks!

> Unlike what you expected, I run rustc main.rs

I don't think that's fair unless you are using debug builds on other langs too. If you wanna use rustc in release mode, try rustc -C opt-level=3 main.rs, it would be a lot faster. --Pro465 (talk) 12:09, 7 September 2023 (UTC)

I retested, now that the interpreter takes 0.2 secs to run and the compiler takes 0.6 secs. --None1 (talk) 12:52, 7 September 2023 (UTC)

what about the other projects? all of them probably could be faster by enabling optimizations (unfortunately I am not experienced enough in them to tell you how to add optimizations) --Pro465 (talk) 13:32, 7 September 2023 (UTC)

Other projects are all either already optimized or doesn't support optimizing, I'm not sure about brainfuck-rs though, I downloaded it through its Windows distribution. --None1 (talk) 13:56, 7 September 2023 (UTC)

OK, thanks and have a great day/night --Pro465 (talk) 14:29, 7 September 2023 (UTC)

oh, mine is terrible at this. even when you set step time to 0. tommyaweosme 13:04, 28 July 2024 (UTC)

Hey this is Sree - I provided the full source for mine, though haven't tried under Windows for years (It should still work though) https://github.com/sreekotay/bffsree

OK, I'll use the source code next time I retest (soon). --None1 (Nope.) 06:45, 13 August 2026 (UTC)

Logarithmic or inverse scale for the bar chart?

That bar chart looks very unclear, because the fast ones are just very short, becoming a horizontal line. Maybe use the inverse of the time(to get the speed) or logarithmic scale. Also have you tested this? -- i  s  l  p  t  n  g  01:20, 17 August 2026 (UTC)

UR right. I'll add your interpreter next time. I'm also trying to add Urban Muller's interpreter if I can change the number of cells. --None1 (Nope.) 05:52, 17 August 2026 (UTC)

I've added inverse and logarithmic charts and tested your interpreter. Your interpreter ran really fast and took only 107ms to run in average. --None1 (Nope.) 11:48, 17 August 2026 (UTC)
