 Sandro | Can someone merge https://github.com/NixOS/hydra/pull/1227 ? | 14:30:40 |
 das_j | It would be benefitial if there was a test for it | 14:32:33 |

| Sandro | My perl knowledge is none existing, so that will probably not happen in the near future | 12:26:22 |
| Sandro | unless I should write a half backed and probably bad test | 12:27:50 |

| 7c6f434c | So, for a given set of derivations to build, bundling them as deps to a single named Hydra job does not help the scheduler at all? (Moving a conversation from ofBorg room — in particular with K900 —about what is «a lot» of really cheap to build packages, and are there any ways to affect it) | 14:07:50 |
 K900 | No, it doesn't | 14:08:01 |
| K900 | Every .drv is still scheduled separately | 14:08:07 |
| 7c6f434c | So only merging into a single multi-output derivation would help (but with other drawbacks, of course) | 14:10:57 |
| K900 | Yes | 14:12:02 |
| K900 | But we don't want to do that | 14:12:05 |
| K900 | It's not like we're hitting any real limit | 14:12:18 |
| K900 | It's mostly just that the queue runner is old and janky and not very fast | 14:12:39 |
| K900 | But it could be made a lot faster | 14:12:44 |
 vcunat | With large number of jobs, I suspect the cost (apart from evaluation) is about S3 queries on all output paths across Atlantic (and serialized, I suspect) and then potentially moving lots of data to/from builders. | 14:15:57 |
| vcunat | * With large number of jobs, I suspect the cost (apart from evaluation) is about S3 queries on all output paths across Atlantic (and serialized, I suspect) and then potentially moving lots of data to/from builders (some of which could again be relatively far). | 14:16:59 |
| vcunat | That's for hydra.nixos.org in particular. Normally you'd probably try putting all the machines close together... | 14:18:36 |
