 immae (he/him) | https://r13y.com/ still mentions #nixos-r13y (cc grahamc (he/him)) | 09:46:34 |
| immae (he/him) | (and congratulations for managing to remove gcc from the unreproductible list btw!) | 09:48:49 |
 @grahamc:nixos.org | Can you send me a pr? Grahamc/r13y.com I think | 11:29:11 |

(and congratulations for managing to remove gcc from the unreproductible list btw!) yay! | 11:44:58 |
| siraben | what was the effect on performance of compiled binaries? | 11:45:16 |
 andi- | In reply to @siraben:matrix.org
what was the effect on performance of compiled binaries? Compilation is now about 10% slower IIRC | 11:46:07 |
| siraben | oh, and are the binaries slower? | 11:46:50 |
| andi- | No | 12:09:29 |
|  justinrestivo changed their display name from justinrestivo to oh caml >>=. | 12:20:52 |
| justinrestivo changed their profile picture. | 12:21:57 |
| justinrestivo changed their display name from oh caml >>= to justinrestivo. | 12:22:24 |
| justinrestivo changed their profile picture. | 12:23:57 |
| immae (he/him) | sure | 12:56:15 |
| siraben | andi-: why does compiling become slower? | 13:01:36 |
| andi- | siraben: the produced GCC binary no longer is PGO optimized. | 13:02:03 |
| andi- | because the PGO stop wasn't reproducible | 13:02:19 |
| siraben | Ah. Is that acceptable for the rest of Nixpkgs? | 13:02:36 |
| andi- | I think so | 13:05:16 |
| andi- | baloo was looking into making it reproducible | 13:05:30 |
| andi- | And I am trying to do the same for python (with little success). | 13:05:43 |

 raboof | that 10% wasn't very scientific btw AFAIK, I tried getting more reliable numbers but it varied wildly so I didn't really get anywhere yet | 11:57:14 |
|  Dandellion joined the room. | 12:13:50 |
 baloo | the 10% depends on the build | 17:01:57 |
| baloo | gcc says 8% | 17:02:06 |
| baloo | I've seen numbers from 7% to 12% https://github.com/NixOS/nixpkgs/pull/112928#issuecomment-778508138 | 17:03:26 |
| baloo | I'd expect cpp builds to be the most impacted. | 17:04:06 |
 afontain | and then you factor in that cpp builds are slow in the first place :^) | 21:32:38 |

|  [0x4A6F] changed their display name from [0x4A6F] to 0x4A6F. | 08:24:18 |
