Two quick points:
- Re Requires.jl, the issue is not Requires itself (that mechanism is fine), the issue is that the way most of us use it causes the code not to be cached. But you could simply define a sub-package and make the
@require @eval using MyRequiresSubPackageand then it would be fully compatible with precompilation. - Measuring load time without measuring TTFX is only half the story. Sure, if load time increases from 20ms to 200ms, that’s bad; but if removing the precompiles causes TTFX to go from 2s to 20s, that’s much worse.
