[PYTHON] Actix-web performance

I was interested in web apps and Rust, so I compared the performance of web frameworks to see how fast they work.

environment

windows 10 pro
Intel(R) Core(TM) i5-7300U CPU @ 2.60GHz 2.71GHz
RAM: 8.00 GB
system 64bit

Web server creation

Web framework to use Rust: Actix-web Python: Flask Julia: Genie

Hello World app creation First of all, Actix

command

cargo new hello-world
cd hello-world

Edit main.rs in \ hello-world \ src.

main.rs

use actix_web::{get, post, web, App, HttpResponse, HttpServer, Responder};

#[get("/")]
async fn hello() -> impl Responder {
    HttpResponse::Ok().body("Hello world!")
}

#[post("/echo")]
async fn echo(req_body: String) -> impl Responder {
    HttpResponse::Ok().body(req_body)
}

async fn manual_hello() -> impl Responder {
    HttpResponse::Ok().body("Hey there!")
}

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    HttpServer::new(|| {
        App::new()
            .service(hello)
            .service(echo)
            .route("/hey", web::get().to(manual_hello))
    })
    .bind("0.0.0.0:8080")?
    .run()
    .await
}

Flask

Create server.py in an appropriate folder.

server.py

from flask import Flask

app = Flask(__name__)

@app.route('/')
def index():
    return 'Hello World'


if __name__ == '__main__':
    app.debug = True
    app.run(host='0.0.0.0', port=8001)

Genie created in Julia

command

julia
using Genie
Genie.newapp("hello_world")

Since the file set is created automatically, exit julia and edit the routes.jl file.

routes.jl

using Genie.Router

route("/") do
  "Hello - Welcome to Genie!"
end

Genie.AppServer.startup(8000, "0.0.0.0")

Now that I think about it, I might have just done the following in julia without creating a fileset. .. .. ..

"Hello - Welcome to Genie!"
end
Genie.AppServer.startup(8000, "0.0.0.0")```

 Leave the three web apps running and use another PC (ubuntu20.04) to measure performance.

# Performance measurement

 Use wrk2.

Use wrk2img to display the graph. https://github.com/PPACI/wrk2img

command

pip3 install wrk2img
#It didn't work so I put on sudo

I will measure it. See below for how to use and view. https://qiita.com/RyujiKawazoe/items/1da4342d8854543ca4cc

command

wrk -U -d 30 -c 100 -R 1000 --latency http://192.168.1.95:8080/ | wrk2img actix_100.png
wrk -U -d 30 -c 100 -R 1000 --latency http://192.168.1.95:8001/ | wrk2img flask_100.png
wrk -U -d 30 -c 100 -R 1000 --latency http://192.168.1.95:8000/ | wrk2img genie_100.png

result of actix

Flask results

Genie results

Flask <Genie <actix, so actix seems to perform better.

Graph when the number of actix connections is increased at the end (10,100,1000,10000)

There is no load up to 100, but it seems to be affected when it reaches 1000.

that's all
