If rust is so great, why is it slower than C and C++?

If rust is so great, why is it slower than C and C++?

Because these tests aren't scientific and don't make sense when used in this way. The site itself tells you this.

It's not great.
It's literally pointless language that will be dead in 10 years.

If you want low level no GC use C++, otherwise Java/Go are plenty performant.
Python/Node.js if you are more interested in development speed.

If you want ugly language with steep learning curve, worse performance than C/C++, no libraries, and SJW community than Rust is for you.

Rustjws BTFO

What's that Apache Portable Runtime that all those superfast C/C++ uses for allocator?

And still rust community works to get best score possible.

...

Because it has to constantly check for code of conduct violations at runtime

kek

[ ] normal kek
[X] MEGA KEK

Common misconception. The Rust compiler can catch 92% of CoC violations at compile time. Runtime checks are minimal.

this is why i cant take anything seriously on Sup Forums.
everyone is retarded, OP being a prime example.

Wins.

No one ever said Rust is great. Its just another reinvention of some wheel.

put me in the screencap

RUSTED.com

Because the borrow checker forces you to structure your program in horrible and inefficient ways.
>immutable by default (without multiple mutable references) in a procedural programming language
absolute insanity.

Compare with with clang for a fairer benchmark

holy shit, rustfags btfo!

Why aren't you using the fastest language on the planet, Sup Forums?

>If you want low level no GC undefined behavior and fast buffer overflows use C++
Yeah, sure.

>If you want low level no GC use C++

Modern C++ has specific functionality for integrating a GC if you choose to do so. The entire point is you can use one when appropriate or manually mange memory for hard real-time applications.

use crystal, it blows everything out of the water

No compilers support that though.

>If rust is so great
>IF

congrats on your absurd amount of memory usage.

Why don't we use java for more high performance programs again?

Someone fill me in, I know nothing about Rust other than it tries to be safer than C++

It's like C++ but with only smart pointers

"put me in the screencap" my arse

and compiler enforced raii

Are you retarded, user?

SJW language with poor performance that exists solely to push a political agenda

Would cause too many Cfag suicides.

go a shit and 5x slower than rust
java isn't in the same category with its huge runtime and memory usage

rust's weakness is complex data structures but it's improving
