 emily | Apple didn't bother with SMT at all | 01:46:38 |
 jade_ | so the second one is QoS Default | 01:46:38 |
 hexa | and the launchd one has background priority? | 01:47:05 |
| emily | wondering how they compare for system responsiveness if you run a build that will eat all the cores | 01:47:05 |
| emily | utility not background but yeah | 01:47:14 |
| jade_ | i was reading stuff in my browser and the computer was not crying | 01:47:22 |
| jade_ | very un-scienticious also because i dont even have my M4 Air plugged in right now | 01:47:42 |
| emily | Lix test suite hasn't made my system chug | 01:47:56 |
| emily | you want some huge Rust build or something | 01:47:59 |
| jade_ | the interesting thing here is that the part that seems to have been affected by the QoS to produce basically the entire difference is installcheck | 01:48:27 |
| emily | hmm | 01:48:37 |
| emily | maybe something to do with spawning a bunch of processes | 01:48:42 |
| jade_ | so not heavy on-cpu stuff necessarily | 01:48:42 |
| jade_ | yeah | 01:48:45 |
 raitobezarius | so the QoS theory is confirmed? | 01:53:11 |
| emily | it's probably like one of twenty things | 01:53:57 |
| raitobezarius | neat | 01:54:22 |
| emily | eventually I will convince someone that Instruments is actually good and snipe them into finding the other 19 :P | 01:54:22 |
| * raitobezarius set someone to emilazy | 01:54:33 |
 EsperLily [she/her] | doesn't it? on darwin, no chroot means the sandbox is ```
(version 1)
(allow default) | 01:56:32 |

(version 1)
(allow default) yes and allow-setuid no | 01:56:45 |
| raitobezarius | basically | 01:56:46 |

| jade_ | theres so many bugs that are just "lol someone needs to spend 2h finding them" that are massive impact :V | 01:57:11 |
| raitobezarius | In reply to @raitobezarius:matrix.org
basically the problem is that chroot or no chroot doesn't tell me if there's a sandbox policy that prevent me from reading outside of the Nix store | 01:57:33 |
| raitobezarius | or the build directory | 01:57:36 |
| raitobezarius | so to simplify things, i can just assume that i can NEVER read outside of these directories | 01:57:46 |
| raitobezarius | which would be the maximum sandbox policy applied | 01:57:54 |
