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.
