I’ve got a macro that wasn’t impacting my project compilation speed much. I added a small feature to it, and now it’s ~50x slower. But at least to look at it, it certainly doesn’t appear as if 50x more work is being done.
Are there any tools I can use to determine why this is the case? After the AST is generated (this part is fast), I’m not sure where things ‘go’, or what tools I might have to identify the source of my slowdown.
