Even 10% makes it a no-go. Even 1%.
D has to be competitive in the most demanding environments. If you've
got a server farm, 1% speedup means 1% fewer servers, and that can add
up to millions of dollars.
You seeing this completely one sided. Even if write barries make code
slower by 10% its a non issue if the GC collections get faster by 10% as
well. Then in average the program will run at the same speed.
