--- Comment #38 from bearophile_h...@eml.cc --- The original D program ( http://forum.dlang.org/thread/efmjlfpehqqfszcrx...@forum.dlang.org ) was about 30 times slower than the equivalent C++ code. Now the D code is only 5 times slower than the C++ code. So the situation is much better now. But the two programs are not exactly equivalent: the C++ code uses a tree-based map while the D code uses the built-in hash-based associative array. --
