Iain's data indicates that it's only a few % of the time taken on

Do you have data that shows otherwise?
Nothing recent, it's mostly from my C++ compiler testing.
But you argued in your blog that C++ parsing is inherently slow, and you've
fixed those problems in the design of D.
And as far as I can tell, you were extremely successful!
Parsing in D is very, very fast.
Yeah, but I can't escape that lingering feeling that lexing is slow.
I was fairly disappointed that asynchronously reading the source files didn't
have a measurable effect most of the time.
so you started you lexing, parsing in seperated threads for each file -
where was synchronization needed, have you measured what parts of the
code makes it like synchron reading - or is it the file reading itself?
