If i have a simple rest api on a server - whats the best way to test how many requests per seconds it can do? I am trying to load test it via bench/vegeta/jmeter etc but my client machine runs out of resources i think before i reach the peak

[Xavier Hanin]

I suggest to have a look at gatling.io, which is asynchronous and doesn’t use threads for the virtuals users, so it’s very resource cheap: https://gatling.io/docs/current/

[Xavier Hanin]

For very simple tests I’ve also found ab useful in the past: http://httpd.apache.org/docs/2.2/en/programs/ab.html

[asad.awadia]

Hmm i ve tried both

[asad.awadia]

I dont think its the tooling - i think its the server/client machine tuning that is not right

[Shawn A]

What does your environment look like? Are you able to spin up additional compute resources in "the cloud"? I've used locust on top of docker swarm to generate 5k TPS no problem.

[asad.awadia]

Right now everything is just on local laptops

[asad.awadia]

Do u have an example?

[Shawn A]

thats not a very good way to test the throughput of your app unfortunately.

[asad.awadia]

Yeah i know lol

[asad.awadia]

That’s why Im posting here

[Shawn A]

You should deploy onto whatever hardware you plan to host your app on in production

[asad.awadia]

My loadtester runs out of resources before i reach maximum throughput on the server

[Shawn A]

Is your server running locally too? Or is that deployed somewhere

[Shawn A]

You'll want to move the load testing tool off your local machine and onto a server or cluster of servers wherever you host your stuff.

[asad.awadia]

I have tried running the server on a simple server on gcp

[asad.awadia]

And then used kubernetes to scale up a cluster to spam it

[asad.awadia]

But still ran out of resources on the cluster before the server starts failing

[asad.awadia]

The instance is a tiny micro instance

[asad.awadia]

And the server is just one endpoint that returns 200

[Shawn A]

It returns a static hard coded 200? It does no other processing?

[Shawn A]

Why would you want to load test that?

[asad.awadia]

Because i want to compare two frameworks

[Shawn A]

Just pick one based on the features you need. You'll be fine.

[earroyoron]

If run out of resources just looks like you need some non-blocking client to attack service… some node.js tool maybe?

[dave]

@asad.awadia are these frameworks already covered by tech empower? might save you some effort 🙂

[asad.awadia]

@dave they are

[asad.awadia]

But I can’t even come close to those results

[asad.awadia]

And also want to do my own verification

[dave]

well, they do have a customised setup (which has taken years to hone into the state that it is now). Since all frameworks are all run on the same hardware under the same* conditions, the results are pretty much relative - so maybe you've already got an pretty good answer as to which one is fastest?

[dave]

they also do a variety of tests, which you'd also have to replicate for real world usage (much more comprehensive than simply returning a 200 🙂 ).

[asad.awadia]

I honestly just want to have a number for reference - A simple vertx or ktor or http4k server with one endpoint returning 200 on a normal aws/gcp instances can handle X requests per seconds

[asad.awadia]

That’s all I want - regardless of whether that’s useful or not :/
