 hexa | it's fine, let's take the perf stuff slow and the regression fixes fast | 12:25:42 |

in a competing builds scenario
There was almost no CPU pressure during the last attempt on that builder.
| 12:27:04 |
| hexa | the lack of timestamps in build logs … sigh | 12:27:21 |
| Vladimír Čunát | But it's possible. The links of FF/TB have been really long lately, and aarch64-linux probably has lower single-thread performance. | 12:27:51 |
| hexa | yeah, I mean, even for my builds the link takes 30 minutes or so on firefox | 12:28:14 |
| hexa | so I wouldn't be surprised about an hour of silence, if that goes slower | 12:28:25 |

283: maxSilent = 14400; # 4h, double the default of 7200s; sometimes needed for x86_64-darwin on hydra
| 12:28:48 |
| Mic92 | maybe one more candidate where it's not read correctly from the derivation? | 12:29:04 |
| hexa | and from nix.conf | 12:29:25 |
| Mic92 | structured attrs would the first thing to check | 12:30:05 |
| hexa | we configure nix.settings.max-silent-time and it just hardcodes 3600 instead | 12:30:33 |
| Mic92 | https://github.com/NixOS/hydra/commits/hydra.nixos.org/ made this and two other limits configureable | 12:44:10 |
| Mic92 | The performance changes are now in staging-hydra.nixos.org branch | 12:44:28 |

| hexa | hm, I saw two chromium builds complete after 1d 1h yesterday | 12:45:46 |
| Mic92 | * The performance changes are now in the staging-hydra.nixos.org branch | 12:47:11 |
| hexa | cancelling jobs seems to work as bad as before | 13:42:42 |
| hexa | meaning I log onto the builder and kill -9 the thing | 13:43:51 |
| hexa | done for the stuck lix builds | 13:44:00 |
| Vladimír Čunát | Before there was usually the problem that other non-cancelled jobs were depending on that particular step. | 13:44:00 |
| Mic92 | I do have a branch flying around that allows to drain builders... I think we can have the same for canceling a build we want to cancel. | 14:18:34 |
| Mic92 | when things calm down | 14:18:51 |
| Mic92 | * I do have a branch flying around that allows to drain builders machines... I think we can have the same for canceling a build we want to cancel. | 14:19:08 |
