So it's certainly possible that such a language would typically result in slower programs. Compilers work best when given full reign with total context, and this language deprives them of that.
However, compilers fail in one important respect: they can't read the programmer's mind and discern their *intent*, which often leads to "fighting the compiler." Ideally this language would have none of that. The compiler would be like your lab assistant, not your boss.
Here's a fun thought: junior programmer writes a high-level version of a function, which works fine but runs slowly. Then they pass it on to the senior programmer, who compiles it to a lower-level language and hand-optimizes the generated code.
(Then, they pass it to the greybeard, who compiles the low-level language to asm and hand-optimizes it into some Story-of-Mel-esque monstrosity. 
)
But the cool thing is that all of these versions are interchangeable. If the greybeard introduced a bug, you can "rollback" to the senior version while you debug. Good tooling could make this painless.
