2024-11-01 21:42:19 +0100 | <tomsmeding> | they are within 5% of each other on my machine |

2024-11-01 21:41:51 +0100 | <tomsmeding> | zzz: what is also confusing is how this one takes 1.3 seconds (which is about 2x as slow as my machine, which is quite to be expected given the cpu freq + age difference), but the previous one with the \case was 7x as slow as my machine |
2024-11-01 21:41:27 +0100 | <zzz> | ok this is weird. let me doublecheck something |

2024-11-01 21:40:04 +0100 | <tomsmeding> | perhaps ghc is less eager to inline across modules, and in one stuff gets inlined and in the other it doesn't? |
2024-11-01 21:39:41 +0100 | <zzz> | ok wait. trying one thing |
2024-11-01 21:39:31 +0100 | <zzz> | yes |
2024-11-01 21:39:22 +0100 | <tomsmeding> | can you reproduce your original measurements :p |
2024-11-01 21:38:03 +0100 | zzz | confused |

2024-11-01 21:30:17 +0100 | <tomsmeding> | can you try my last paste? |
2024-11-01 21:29:56 +0100 | <zzz> | i consistently get better results for compiled rnf |
2024-11-01 21:29:29 +0100 | <zzz> | one file for each version |
2024-11-01 21:29:28 +0100 | <tomsmeding> | zzz: https://paste.tomsmeding.com/WGmJJRuD |
2024-11-01 21:29:12 +0100 | <zzz> | tomsmeding: oh, i did that so i could easily share it. i ran separate files |
2024-11-01 21:28:52 +0100 | <monochrom> | That is strange. |
2024-11-01 21:28:26 +0100 | <tomsmeding> | are you perhaps testing one version with it all in one file and one version split over multiple files? |
2024-11-01 21:28:08 +0100 | <tomsmeding> | zzz: if I compile your code as-is (but do put it all in one file), I get similar timings too |
2024-11-01 21:27:47 +0100 | <zzz> | monochrom: 8GB Ram :) |
2024-11-01 21:26:57 +0100 | <monochrom> | OK I'll stop until I think up a better joke! |
2024-11-01 21:26:18 +0100 | <monochrom> | What if the web browser already eats up 0.4999GB and the OS eats up the rest :) |
2024-11-01 21:25:47 +0100 | <zzz> | tomsmeding: i don't understand why in your test the difference between deepseq and rnf disappears |
2024-11-01 21:25:10 +0100 | <tomsmeding> | case 1 and 2 run lean |
2024-11-01 21:25:06 +0100 | <tomsmeding> | monochrom: that would be for case 3 only |
2024-11-01 21:24:54 +0100 | <EvanR> | intel celery |
2024-11-01 21:24:48 +0100 | <monochrom> | OK now I'm hoping "oh it only has 0.5GB RAM so yeah it's thrashing" |
2024-11-01 21:24:26 +0100 | <tomsmeding> | but yeah with a CPU of that class I would not expect a 7x difference, but I guess it could be |
2024-11-01 21:24:20 +0100 | <zzz> | 4 cores |
2024-11-01 21:24:12 +0100 | <zzz> | plugged in, not sure if it's throttling |
2024-11-01 21:23:38 +0100 | <tomsmeding> | that can still mean various CPUs it seems |
2024-11-01 21:23:36 +0100 | <EvanR> | "did you check if it's plugged in" |
2024-11-01 21:22:54 +0100 | <zzz> | HP ProBook 440 G4 |
2024-11-01 21:22:23 +0100 | <zzz> | tomsmeding: not sure, it's not mine. sec |
2024-11-01 21:21:52 +0100 | <monochrom> | I was hoping "brand new laptop using the brand new intel lake cpus so yeah it's a well-known regression" >:)\ |
2024-11-01 21:21:36 +0100 | <tomsmeding> | O.o |
2024-11-01 21:21:24 +0100 | <dolio> | I was helping someone out a week or so ago, and they were doing something on their laptop, and my 10 year old desktop might have been that much faster when I tried it. |
2024-11-01 21:21:18 +0100 | <tomsmeding> | what model number? |
2024-11-01 21:21:08 +0100 | <zzz> | tomsmeding: old hp laptop, core i5 7th gen |
2024-11-01 21:20:45 +0100 | <tomsmeding> | zzz: if it's a laptop, are you sure it's not throttling? Is the power cable attached? If it's intel, is turbo boost enabled and does the cpu reach similar frequencies for both tests? |
2024-11-01 21:20:19 +0100 | <dolio> | I don't know about that. |
2024-11-01 21:20:03 +0100 | <tomsmeding> | my CPU is like 7x as fast as yours? That feels unlikely |
2024-11-01 21:19:44 +0100 | <tomsmeding> | okay so they are at least the same but 1. why are they slower than your code, and 2. what CPU is that, I know mine is fairly fast but _this_ fast? |
