Hi Niyazi, we are using our binaries two ways:
1. if possible in docker (95% of time), so we like our docker images as small as possible
2. if not possible, as background services, here we do not case about size of those binaries, but we use those small binaries, because we already have them

We use UPX the standard way, so simply upx binary_name and that’s it. No special options.
