I guess I’m a couple of years behind, but I just discovered this nice post from @tim.holy and @NHDaly. It’s already very helpful as is, but then I get to this flamegraph image
with the caption
Here, the red boxes correspond to
MethodInstances which cannot be “naturally” precompiled. This occurs when the method is owned by one module but the argument types are from another unrelated module. We’ll see how to deal with these in later installments.
I have a flamegraph with some of these red boxes, but I don’t see a later installment addressing this. Was there one? If not, is this covered in docs somewhere? Or maybe other approaches are now preferred?

Oh, good point. Yes, I just decided to fix precompilation instead of writing another blog post 
. The bottom line is that the red bars aren’t problematic anymore if you use PrecompileTools; fixing those red bars is basically what PrecompileTools is about.
