Shower Than C Extension #149

Open arshidkv12 opened 6 months ago

arshidkv12 commented 6 months ago

Hi I tested with xdebug profile option with grind cache. Functions are slower than c. How to speed up?

jmjoy commented 6 months ago

What about the data?

arshidkv12 commented 6 months ago

cachegrind

PHP code:

for ($i=0; $i < 1000; $i++) { 
        say_hello("sdf"); //rust
        strpos("sdfsf", "d", 1); //c function
}

Rust:

pub fn say_hello(arguments: &mut [ZVal]) -> phper::Result<()> {

    Ok(())
}

0.18 > 0.11

Why does the Rust function take longer than the C complex O(n) function?

How to optimise it?
