Go 1.16 was recently released. As I’m deploying Go apps to edge devices and doing updates over cellular, I’m always interested in binary size, and pleasantly surprised with this release that ARM binaries for one project actually got smaller:
Go 1.17 was recently released. I like to compare the output binary sizes of Simple IoT just to make sure things are not getting significantly bigger:
| binary | size Go 1.16 | size Go 1.17 |
|---|---|---|
| x86_64 | 23134208 | 22016000 |
| arm | 19333120 | 19464192 |
| arm xz compressed | 4839476 | 4690792 |
Less than 5MiB for a compressed SIOT binary is still good – this size is still practical to deploy app updates over Cat-M modems.
Go 1.18 is now released. Generics, 20% improvement for ARM64, etc – good stuff. This further enforces @khem’s conclusion that ARM64 is the place to focus going forward …
