 @grahamc:nixos.org | yeah, there are a number of performance improvements that could probably be made | 15:06:12 |
 Domen Kožar | it's probably due to compression taking so much of the CPU | 15:06:39 |
| Domen Kožar | it's copying now for 10min | 15:07:04 |
| Domen Kožar | 😱 | 15:07:27 |
| @grahamc:nixos.org | compression does happen at a variety of levels | 15:08:06 |
| Domen Kožar | ah, I meant xz for the binary cache | 15:08:25 |
| @grahamc:nixos.org | yeah, but it is actually probably worse | 15:08:32 |
| @grahamc:nixos.org | like we use SSH compression too | 15:08:36 |
| Domen Kožar | right | 15:08:49 |
| Domen Kožar | grahamc (he/him): how can we prioritize that patch of yours? :) | 15:09:08 |
| @grahamc:nixos.org | frankly, right now, finding someone to pay for the time to do it 😓 bootstrapping a business with a 1y/o makes it hard to get focused time on things like that otherwise | 15:10:02 |
| Domen Kožar | how much time is needed to shape it up? do you have a rough estimate? | 15:10:25 |
| @grahamc:nixos.org | I don't have an estimate really, it was extremely proof-of-concept | 15:10:45 |
| @grahamc:nixos.org | but I could try and come up with one | 15:10:51 |
| Domen Kožar | hmm | 15:11:42 |
| Domen Kožar | well if you come up with one that would help, I really think this would give us a huge boost | 15:12:00 |
| Domen Kožar | maybe just crowdfund it | 15:12:14 |
| Domen Kožar | savings are enormous, 100MB should compress in like 20s instead of 12min | 15:14:45 |
| @grahamc:nixos.org | I think it is a bit quick to jump to saying it is compression, but there is definitely a lot of benefit from moving cache uploads from central machine to the builder | 15:18:36 |
| Domen Kožar | it's I/O + compression | 15:19:03 |
| Domen Kožar | not sure what else it would be, the job was stuck in "receiving outputs" for 12min, that should otherwise be independent of hydra | 15:19:46 |
| @grahamc:nixos.org | well ... I wouldn't jump to that, personally, so soon -- but perhaps so :) | 15:20:14 |
| Domen Kožar | I reserve the right to be wrong! | 15:25:34 |
| Domen Kožar | about bootstrapping a business .. yeah 3 years in it's still hard :D | 15:35:55 |
| @grahamc:nixos.org | hey 3 years is supposed to be that magic number of "if you made it this long you've probably got something" | 15:36:50 |
 Vladimír Čunát | some debt at least | 15:38:17 |
| Domen Kožar | :D | 15:40:45 |
| Domen Kožar | I mean given how crazy the dev market is these days it's a huge opportunity cost | 15:41:04 |
| Domen Kožar | but I'm lucky to be a cheap fuck so whatever, I prefer to improve Nix :) | 15:41:30 |
| @grahamc:nixos.org | yeah, I could make way more money if I went and got a regular job | 15:42:12 |
