bombardier VS script

Testing Tool: Bombardier (for simulating high-concurrency requests)

Why? There is a ready script for that https://github.com/codesenberg/bombardier

You could try to just blast it with wrk or bombardier. Can easily get around 50k requests on consumer machine.

Sorry if this is a bit out of subject but this is a question how to deploy a Rust API. Just finished a GraphQL API and benchmarking when spawn locally on my Apple M1 I get 30k req/sec (super fast!) but when deployed to digitalocean, with a Docker image, on any of their apps size I get about ~200/sec, up to 500/sec max (60x less!) if running bombardier from the same network. I tried Heroku which gets me similar results as well.

Podes utilizar algo como o bombardier.

For testing, I’ll use the Go Bombardier package, which runs 5000000 requests with 125 concurrent connections with the following command:

That's why I plan on migrating all my shell scripts to Golang programs f.ex. using https://github.com/bitfield/script -- it already has a number of simulations of shell commands and I'd contribute others if I had the time.

sh / bash / zsh scripts are just fragile and that's the inconvenient truth. People who devised the shell interpreters had good intentions but ultimately their creations grew to a scope 1000x bigger than they intended, hence all the "do X but if Y flag is set then do Z... unless flag A is also set in which case do Y and part of Z".

It's horrendous and I seriously don't get what's so difficult in just coding these scripts in a programming language that provides single statically linked binaries (like Golang) and just distribute it with your images -- or run them in CI/CD and have init containers and never include them in the images in the first place.

Inertia, of course. But I'll be actively working against it until I retire.

I use Go. You can run scripts with go run directly, and this package makes shell tasks easy: https://github.com/bitfield/script

If you're not deeply familiar with Go there is one detail missing from this post (though it's in the script README) - what a complete program looks like. Here's the example from https://github.com/bitfield/script#a-realistic-use-case

    package main

Imho also worth mentioning: https://github.com/bitfield/script
