 Mic92 | It's good to see that the UI somewhat scales | 09:55:39 |
| Mic92 | Do you have numbers how fast github is able to build those 1000 derivations? | 09:56:47 |

Do you have numbers how fast github is able to build those 1000 derivations? Recently, we switch to my own self-hosted github runner (Ryzen 5600X 6C/12T, 16GB) and it takes a few minutes at most (depends on what is already available on cachix) | 10:40:26 |
| Mic92 | Ok. but how long does a full rebuild takes? | 10:51:50 |
| Mic92 | There is also some caching done after a second build | 10:52:30 |
| Gaétan Lepage | It took 1 hour and 48 minutes | 11:13:58 |
| Mic92 | How long on your server? | 11:33:02 |
| Gaétan Lepage | <10min | 12:26:53 |
| Mic92 | You probably also didn't had to do any remote builds, which also seem a bottleneck | 12:36:39 |
| Gaétan Lepage | Yes, it looks like I could run nix flake check --all-systems locally even though I had no remote-builders | 12:43:00 |
| Mic92 | what are those module- packages? | 12:49:27 |
| Mic92 | It looks like nix-eval-jobs report those to be not cached. | 12:49:40 |
| Mic92 | Also cachix than says during upload they are. | 12:50:05 |
| Mic92 | mhm locally they are considered cached | 12:56:44 |
| Mic92 | Another bottleneck might be also that it update's the job status on github for every derivation. | 13:08:49 |
| Mic92 | All in all as of today, I haven't really optimized it for these types of workloads. Hydra might be still the better choice for large package sets. | 13:15:21 |

 K900 | Does anyone have a build this entire flake and push to cache action I can steal? | 08:33:46 |
 raitobezarius | a single action or a github action code to do both? | 09:01:44 |
| K900 | Either works | 09:06:57 |
| K900 | Basically I just want something I can drop into kde2nix to have a binary cache for it | 09:07:06 |
| K900 | Without spending half a day on figuring out github actions | 09:07:15 |
 aidalgol | I think that's what cachix-action does with a post hook. | 09:28:32 |
| aidalgol | We use it in the GH action for vs-overlay. I think it uploads everything that got built in your action, so it should work with the flake build command, not just nix-build. | 09:30:48 |
| aidalgol | So I think this would do what you want.

| K900 | Hmm | 09:31:57 |
| K900 | Yeah looks stealable | 09:31:59 |
| aidalgol | Er, that would only build the default package, won't it... How do you build an entire flake? | 09:32:45 |
