 Tristan Ross | Native, I can't do emulation | 13:44:07 |
| Tristan Ross | Emulation doesn't quite work with a 64k page size on Ampere | 13:44:18 |
| Tristan Ross | Cross compiling though took 40 minutes on Ampere | 13:44:30 |
| Tristan Ross | Native building took like 9 hours and 30 minutes | 13:44:43 |
| Tristan Ross | * Native building took like 9 days and 3 hours | 21:32:37 |

 DavHau | I'm cross compiling my starfive as well. 9 days sounds crazy. Is this due to slow flash IO, or is the CPU the limiting factor? | 03:22:39 |
 Alex | IIRC it's mostly CPU-limited. | 03:34:10 |
| DavHau | Wow, this sounds unreal? Is it just that compilers etc. are not optimized to run on riscv? | 03:53:33 |
 dramforever | the visionfive 2 is just not a great cpu | 05:13:48 |
| dramforever | i mean the jh7110 on it | 05:14:35 |
| dramforever | they had to rush the release to be before the th1520, otherwise they couldn't even have the claim to be the fastest riscv sbc at release | 05:15:21 |
 @lotte:chir.rs | io speed is quite good | 05:22:53 |
| @lotte:chir.rs | especially if you have an nvme ssd | 05:23:04 |
| dramforever | it's not great for an nvme, not even great for pcie2.0x1 but it's much better than any sd card | 05:24:17 |
| dramforever | get a cheap 16G optane | 05:24:31 |
| @lotte:chir.rs | i slapped my old laptop ssd in there | 05:25:15 |
| @lotte:chir.rs | (compared to similar devices) | 05:25:38 |
| @lotte:chir.rs | my laptop had an early m.2 nvme ssd | 05:26:24 |
| dramforever | the pcie is all in all pretty good | 05:26:30 |

| @lotte:chir.rs | but yeah those claims were just Wrong | 05:28:49 |
| @lotte:chir.rs | i can barely get it to half speed to the rpi4 without overclocking | 05:29:05 |
| @lotte:chir.rs | it’s still pretty good simply because you can use system storage that doesn’t explode randomly | 05:29:33 |
