Can we discuss this shit? Apple’s fucking language for apps is becoming a serious contender to c

There are some ways to try damage control without coming out as actual retards, you know.

I have no stake in this and don't use either language

Sure thing, Tim.

How show can a language be??

It's over. C is kill.

A MINUTE AND FIFTEEN SECONDS

>Double to triple the slowness sometimes
>37 times the slowness with regex

Swift is quite fast, but more in the Rust/Go/Java tier than directly comparable to C/C++.
The only built-in regex in swift is NSRegularExpression, which is based on the rather but very unicode savvy) ICU regex engine, and is further slowed further by Strings needing to be bridged to NSStrings to use it. Since C doesn't have a built-in regex engine, I suspect they're using PCRE, which is lightning fast and only optionally handles unicode to be even faster.
Now that swift Strings exclusively use UTF-8 buffers, they can be converted to C strings with (almost) no overhead. This means if you need a faster regex, you can include PCRE, and use it directly for basically equivalent performance.

That's finally it. C is done for.

> but more in the Rust
Nice try. Swift manages to 1-up C++ in one occasion but always gets beaten by Rust.

>comparing rust to go and java

Quite. Rust should be in the trash on its own.

That's a pretty good sign this is a toy benchmarking site that rust shills have spent a lot of work gaming. Rust performance in general is nowhere near C/C++.

The funny shit is JavaScript and meme languages etc are faster than most languages in regex

Why do several of the faster runs use more memory too

Do you get paid to relentlessly spread fake news?

Almost all regex engines are written in C or C++, which is called into from the higher level language. So this is mostly just comparing a bunch of different C/C++ code + FFI overhead.

how does Rust vs C++ look?

Similar, with Rust winning in one more test.

Rust, like most languages, is just on a different planet compared to C/C++. If you care about perf, you use a fast language, and Rust isn't it.

You tried this before, refer back to , and

Benchmarks are just lies and disinfo in a nice package with a bow on top. Only real programs can actually compare language speed, and Rust doesn't have any of those.

Sorry, honey facts don't care about your opinions.

Basically every common unix utility has been rewritten in Rust by someone, and the Rust one is almost always faster

Yeah it's usually much better, see ripgrep

I honestly thought it wasn't THAT bad.

Any improvement a Rust program makes over the equivalent C program can be ported to C, but not vice versa. Rust is incapable of expressing most of the control flow constructs that make C fast.

That really isn't any more of a contender than say C#.

Go back to your 6 fps games

Why nothing matches the speed of C/C++ despite their old age? How comes nothing new beat them?

Rust

Heavy compiler optimizations for C/C++, most new languages choose GC,OOP,inmutable data,heavy concurrence,dynamic types,Virtual machine or interprete and other features instead of speed.

LLVM backend open new generation for high performance languages, Swift/Rust choose don't use GC or Manual memory just Zig begin same speed as C

Because they had decades and millions in funding to optimize compilers.
