Crystal vs. Node.js vs. Golang vs. Julia vs. Rust vs. LuaJIT vs. C Fibonacci Benchmark
- rubyfan 10y agoI don't love the conclusion, a single Fibonacci benchmark is fairly light evidence to blanket state Crystal is as fast as C. It's also fairly toothless on comparison of other languages.
- FourierT-form 10y agoCOUGH Tail recursion COUGH
- steveklabnik 10y agoHow was this stuff compiled? There's no way to reproduce these numbers without compiler flags, at least. For example, with "rustc fib.rs", I get 10 seconds as a runtime. With "rustc -O fib.rs", to turn on optimizations, I get 0.034s. This makes me pretty sure that they did not turn on optimizations, which means the Rust numbers are very misleading, and possibly, the other languages as well.
- chrisdouay 10y agoI get 0.034s => this means the compiler run the code and puts directly the result in the binary file. So, when you run the binary, it only println(result)
- leovonl 10y agoIf you compile the Rust example with optimization (-O) it just throws the result away, which gives the ~0.030 time chrisdouay found. However, if you add a println!() around it, it has to calculate the result. Here's the running time: > time ./fib 1134903170 real 0m2.242s user 0m2.240s sys 0m0.000s I tried the C example as well (with -O2) and found this: > time ./cfib 1134903170 real 0m4.671s user 0m4.670s sys 0m0.000s So.. which one is faster again? This "comparison" unfortunately seems too naïve to not be on purpose - no analysis, no real discussion, not even some reasoning about the defaults and why the big difference in numbers. It seems to be just looking for views/comments (even if negative) without any intention to produce real content. What worries me are the ones that will take this for a real benchmark and just "share on facebook" and spread more disinformation.
