Some tech exploration 🗺️ 🕵🏻 ✨

Simple test to explore new tech and compare languages.

My hope was that I'd write good Rust, but up to this point, my Go is faster than my Rust, something's fishy. 🐟🥹

I'm open to suggestions on how to fix my Rust code to make it faster.

Starting

1. Start the postgres db with docker, it will start with the default credentials.

docker-compose up -d

2. Starting the node server (:3001)

cd ./proj-node
npm i
npm start

2. Starting the go server (:3002)

cd ./proj-go
go run ./server

3. Starting the rust server (:3003)

cd ./proj-rust
cargo run

Testing

1. Either using the test calls defined in ./test.http
2. Or what I used for benchmarking, cassowary, seems good. Install it with npm i -g cassowary (might need sudo) and then, for example:

cassowary run -u "http://127.0.0.1:3001/get_first_values?n=5000"
cassowary run -u "http://127.0.0.1:3002/get_first_values?n=5000"
cassowary run -u "http://127.0.0.1:3003/get_first_values?n=5000"
