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 |
