Thank you for your information. It seems that the performance of 
D is not very bad compared with low-level languages. It may be 
between C and Java or. Net. As a normal production tool, there 
should be no problem. Thank you for your reply. Best regards

Not sure what you mean by drawing a distinction between D and 
low-level languages. If you translate a piece of C code into D 
(it doesn't even require much translation since the syntax is 
similar) and compile it, you'll get the performance of C. If D 
code is slower than C, it's because you've chosen to write slower 
code for convenience/safety reasons rather than performance.

I want to use d to develop my own DSL, which requires the 
performance guarantee of the original language to avoid the 
performance loss of the upper DSL. In addition, I don't want to 
implement an extremely complex garbage collector by myself, so I 
want to find a language with automatic collection function. After 
comprehensive consideration, I still think that D is very 
suitable in this respect. It is not cumbersome, fast, and the 
basic library is relatively complete.

In optimized settings, D doesn't have bounds checks or integer 
overflow checks, it can easily be the very same performance as C 
and C++.

You can use AMD CodeXL / Intel Amplifier and all kinds of 
profilers like you would in C++.

If you write the same code in the same way, you'll get identical performance 
between C, C++, and D. Note that they use the same optimizers and back ends.
