do you compare dmc based and visualc based dmd builds?
the vc dmd build seems to be always two times faster - how does that
look with your optimization?

I just reported this compile speed killer:

It has a big impact on some of the

Hash collisions are not the problem - I sized the hash bucket
array to make it fairly sparse. Neither is the hash algorithm.
The slowness was in the frackin' convert the hash to an index
in the bucket, which is a modulus operation.
Thankfully in that thread Paul Hsieh has

It's not the hashing that's slow. It's the lookup that is.
By different hashing scheme I meant different strategies in

Then it's past due to finally stop the madness of modulo prime table and
use a power of 2 size. In

It would be most interesting to see just what it was that made the vc build
faster.
But that
