 emily | as in it schedules on the threads of a core separately yeah | 01:45:52 |
| emily | which is not good | 01:45:54 |
 hexa |
EAS on SMT is not supported.
| 01:46:05 |
| hexa | yeah | 01:46:10 |

| jade_ | that's insane | 01:46:16 |
| emily | though idk if anyone really made SMT scheduling very good | 01:46:24 |
| jade_ | second one is nix-daemon --daemon running in my terminal, first one is nix-daemon via launchd | 01:46:32 |
| 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 |
