Load tested my Django site

Benchmark HTTP Latency with wrk

 

Recently I started reading through Actix-web, Django,tokio etc, so thought of bench marking the latency. Started with Django as it is pretty easy get started and its in python.

 

looks like wrk ( https://github.com/wg/wrk )  is a good tool to start with. 

"wrk is a modern HTTP benchmarking tool capable of generating significant load when run on a single multi-core CPU. It combines a multithreaded design with scalable event notification systems such as epoll and kqueue."

Installation also pretty easy in Ubuntu:

1. sudo apt-get install build-essential libssl-dev git -y

2. git clone https://github.com/wg/wrk.git wrk

3. cd wrk/

4. sudo make

5. sudo cp wrk /usr/local/bin

Run your Django server using 

python manage.py runserver

 

then another terminal you can run your wrk as below

 

wrk -t12 -c400 -d30s --latency http://127.0.0.1:8000

 I only had single page and not much custom files in the Django and not data base request. Not sure this is a good response .. Please share your comments.

 Also got something like this Django logs as well.

[27/Mar/2021 17:39:14] "GET / HTTP/1.1" 200 196
[27/Mar/2021 17:39:14] "GET / HTTP/1.1" 200 196
Exception happened during processing of request from ('127.0.0.1', 33856)
[27/Mar/2021 17:39:14] "GET / HTTP/1.1" 200 196
[27/Mar/2021 17:39:14] "GET / HTTP/1.1" 200 196

I am planning to try this same experiment with actix-web and Rust , will share once I have something..

 

Yew App - Sudoku solver

How would be a Yew app Sudoku solver ?

sudoku solver can  basically be  a backtracking algorithm . Last month I implemented a Rat-Maze problem solver with Yew App. But it does not look visually much attractive to some of my friends. So thought of doing a sudoku solver with same code modifying the logic for sudoku.

Rat-Maze problem - Yew app - PART2

Rust Yew app:

Last week I wrote about the  Rat-Maze problem - Yew app.

Writing code  in Rust programming language is always fun and a learning.So thought of making some enhancements to the yew app 

1. add colors to the cells

2. after solving the path, change the color of the cells in the path. ..etc

This gave an opportunity to work with CSS and Yew. I think still there is no full support for CSS from Yew as you might have seen in React. But I was managed to change the color with "class" property in CSS.

index.css

.game-celluley {

display: inline-block;

width: 20px;

height: 20px;

border: 1px solid #ccc;

background-color: yellow;

text-align: center;

}

.game-celluleg {

display: inline-block;

width: 20px;

height: 20px;

border: 1px solid #ccc;

background-color: green;

text-align: center;

}

lib.rs

html!{

<div key=x class=format!("game-cellule{}",cell_color)>{ cell.value } </div>

}
