Yep, that's it.

I've tried commenting out all "render" call so I have no diet 
templates and I save 1 second of total time (10.5 to 9.6) and 
it's still the linker that takes all the time.

I looked at the gold linker and it's already a possible 
configuration with Gentoo Linux! I've switched and it now 
compiles and link in 4 seconds! Yah!

But I don't want to switch my whole system to use gold, is there 
a way to configure dub or dmd to use usr/bin/ld.gold instead of 
/usr/bin/ld ?

Thanks!
