| 2025-01-04 00:02:21 +0100 | <haskellbridge> | <magic_rb> The exists function does nothing else, it takes a Int, accesses the vectors from behind a STRef and then returns a Bool |
| 2025-01-04 00:01:41 +0100 | <monochrom> | or rather, s/there should not be/that should not be the cause of/ |
| 2025-01-04 00:01:40 +0100 | <haskellbridge> | <magic_rb> Which adds up |
| 2025-01-04 00:01:36 +0100 | <haskellbridge> | <magic_rb> Yes but im pulling out the Int from it, doing some compressions and then returning a Bool to the calling code saying "yep exists" and doing that hundreds of times per frame |
| 2025-01-04 00:00:21 +0100 | <monochrom> | If you have an unboxed vector and it's mutable and you are in ST/IO modifying it in-place, there should not be that much allocation, at least not allocation a whole new copy of the whole vector. |
| 2025-01-03 23:59:11 +0100 | <haskellbridge> | <magic_rb> Itll be syntactic hell but ive never done that so i wanna try |
| 2025-01-03 23:59:00 +0100 | <haskellbridge> | <magic_rb> Ill try to avoid boxing in exists next, working with unboxed types |
| 2025-01-03 23:58:44 +0100 | <haskellbridge> | <magic_rb> Right i dont need that, or rather dont want that |

| 2025-01-03 23:58:12 +0100 | <monochrom> | boxed is the only one that supports laziness. |

| 2025-01-03 23:57:47 +0100 | <monochrom> | storable and unboxed are pretty much on par. storable supports user-defined types more easily. |
| 2025-01-03 23:57:12 +0100 | <haskellbridge> | <magic_rb> for rendering code or something |
| 2025-01-03 23:57:05 +0100 | <haskellbridge> | <magic_rb> maybe doing storable and reading the pointers? i was hoping to have the sparseset accessible from both Haskell and native code |
| 2025-01-03 23:56:44 +0100 | <haskellbridge> | <magic_rb> but exists is a really frequently used function so it needs to be very snappy |
| 2025-01-03 23:56:28 +0100 | <haskellbridge> | <magic_rb> yeah i know |
| 2025-01-03 23:55:51 +0100 | <monochrom> | boxed takes more memory than unboxed, namely, one more pointer. |
| 2025-01-03 23:54:17 +0100 | <haskellbridge> | <magic_rb> maybe if i can work with the unboxed values directly? though thats extremely clumsy |
| 2025-01-03 23:52:04 +0100 | <haskellbridge> | <magic_rb> might be better to make the metadata vectors boxed? hm |
| 2025-01-03 23:51:40 +0100 | <haskellbridge> | <magic_rb> damn |
| 2025-01-03 23:51:38 +0100 | <haskellbridge> | <magic_rb> it has to box |
| 2025-01-03 23:51:36 +0100 | <haskellbridge> | <magic_rb> all the vectors are unbox, right thats why the allocs |

| 2025-01-03 23:51:03 +0100 | <haskellbridge> | <magic_rb> still |
| 2025-01-03 23:51:01 +0100 | <haskellbridge> | <magic_rb> and somehow overhead in exists |
| 2025-01-03 23:50:47 +0100 | <haskellbridge> | <magic_rb> which suggests that there is overhead from PrimMonad |
| 2025-01-03 23:50:37 +0100 | <haskellbridge> | <magic_rb> i removed some of the inline pragmas, around exists and got https://paste.tomsmeding.com/lA8DAs9V |

| 2025-01-03 23:47:05 +0100 | <haskellbridge> | <magic_rb> maybe i ought to move into games, though this is a general "why is my haskell code horribly slow" question :) |
| 2025-01-03 23:46:21 +0100 | <lambdabot> | Done. |

| 2025-01-03 23:44:03 +0100 | <haskellbridge> | <magic_rb> right and my physics system writes even positions that are equal so there is constant churn |
