 Randy Eckenrode | There is actually a flag for ld64 to limit LTO because it’s too slow even for upstream. | 14:31:18 |
 eveeifyeve | I would say it would take a day to build at least right? | 14:31:45 |
| eveeifyeve | * I would say it would take a day to build at least right just assuming? | 14:31:57 |
| eveeifyeve | I was thinking of giving it a crack of a build overnight while I am sleeping. | 14:32:16 |
| Randy Eckenrode | Maybe. For Hydra, that’s going to be even worse. They’re still using M1s. I have an M3 Max with more RAM. | 14:32:44 |
| eveeifyeve | * I was thinking of giving it a crack of a build overnight while I am sleeping just to try and see If I can spot any issues. | 14:32:49 |
| eveeifyeve | I have a M4 macbook pro with 16gb of ram. | 14:33:05 |
| eveeifyeve | I hope that is enough... | 14:33:22 |
 Ihar Hrachyshka | I have my own machine(s) so it's not that big of a deal (few hours) | 14:34:18 |
| eveeifyeve | But I should look into having a remote builder using my old M1 and M2 macbook pros with 8gb of ram. | 14:34:22 |
| Randy Eckenrode | Darwin with LLD by default should be better, but that’s a post-Swift activity. | 14:34:34 |
| eveeifyeve | * But I should look into having a remote builder using my old M1 and M2 macbook pros with 8gb of ram. The only problem is my M1 has a kernel issue and M2 I need to interact with it via a dongle. | 14:35:03 |

| Ihar Hrachyshka | it was ~2.5h on m4 mac mini with 32gb ram for firefox. | 14:35:28 |

 Austin Horstman | yeah i have a m4 max with 64 gb ram and it took that 10h :S | 14:37:29 |
| eveeifyeve | That will give me a total of 4+4+4=12 performance cores 4+4+8=16 efficiency cores and 32gb of ram across the builders. | 14:37:41 |
| Ihar Hrachyshka | this is... not normal / not what I would expect | 14:37:46 |
| eveeifyeve | * That will give me a total of 4+4+4=12 performance cores 4+4+8=16 efficiency cores with 28 cores in total and 32gb of ram across the builders. | 14:38:06 |
| Ihar Hrachyshka | I may measure some builds this week then. maybe something gets stuck during build and it's not about waiting longer. | 14:38:42 |
| eveeifyeve | Which considering if I can get those two macbooks working and in a tailscale or something would be great for me building stuff. | 14:38:59 |
| eveeifyeve | All I am missing now is a linux machine to build stuff..... | 14:39:11 |
| Ihar Hrachyshka | you can use multiple builders but can't parallelize a huge build like firefox across machines sadly | 14:39:28 |
| eveeifyeve | Sadly 😥 | 14:39:59 |
| eveeifyeve | Hang on isn't there something like enableParallelBuilding which is enabled by default or it was at least was. | 14:41:58 |
| eveeifyeve | * Hang on isn't there something like enableParallelBuilding which is enabled by default or it was at least was??? | 14:42:03 |
 K900 | That doesn't do what you think it does | 14:42:37 |
| Ihar Hrachyshka | it's parallel building like "use more cores on the same machine, make -j etc." | 14:42:39 |
| Randy Eckenrode | That passes the equivalent of -j $CORES. | 14:43:08 |
| Randy Eckenrode | Were you building other things? Nix is awful on workstations because it will pass -jX to X builds and spike your load average to something horrible. | 14:44:12 |
