Everything is slower than C (I haven’t seen a benchmark yet where a language bests C; even hand-crafted ASM ceded the high ground decades ago when compilers got better than human assembly programmers), but then, C compiler technology has had literally 40+ years to mature.
Go and Java (once warm) do pretty well, but absolutely give up execution speed for coding simplicity and (in Go’s case, anyway) speed. Nim is young; I’m curious to see how it matures. They’re having a bit of a performance crisis at the moment, but assuming they get past that it seems like a fair middle ground between Go’s simplicity and Rust’s bare-metal performance. Then again, manual memory management was absolutely my least favorite thing about C and is what eventually drove me away; worst. Boilerplate. Ever. Even worse than Go’s error handling (which they almost fixed and looks like will be addressed within the next free releases). Anyhoo, going back to that shit is going to be a hard pill to swallow.
Rust is still having its honeymoon, and is the hip language of the decade now. We’ll see!
Go, Java, and Nim (in most cases) are all memory safe but are generally slower than C or C++ due to the ways they achieve memory safety.
Rust’s memory safety approach is zero-cost performance wise, which makes it practical for low level, high throughput, and low latency applications.
