As you can see the website claimed that its compiler is "200x faster" than C compilers, while neglecting to mention that it merely translates V code to C, so you still have to
run a C compiler.
"400 KB compiler with zero dependencies" (apart from a C compiler and libc).
"As fast as C" - a lie.
Apart from deceptive marketing, there were serious issues with the code quality of the compiler:
>"As fast as C" is not a lie. It literally translates to C.
No, just because it outputs C it doesn't mean it's as fast as hand-written C. Using that logic, every language that outputs machine code is as fast as assembly, which is obviously not true.
If you look at the C that's generated using -keepc flag, I think you will be hard pressed to find any glaring inefficiencies to "hand coded C"; especially none of which GCC optimization wouldn't handle with -prod compiler flag. Even if there were, for the very large majority of users who are not highly proficient in C (which is becoming more and more common these days - Grey beards are rare), the V way is going to outperform novice to intermediate-skilled C programmers hands down.
It wasn't always like this. Back in 2019, its website looked like this:
