Gor VS locust

I love to see more activity in this area!

I'm maintainer of GoReplay https://github.com/buger/goreplay and work in this area for the last 10 years.

It is quite hard problem to solve, because you have to deal with state difference between test and production environments. Love your approach to mocking dependencies, and leveraging OpenTelementry. It potentially can solve some of state issues. But still require modifying user code. I wonder if it can be done purely using OpenTelementry (e.g. you depend on typical OTel setup), and then read the data directly from OTel DB.

Cheers!

I put `top` command here so you can test my code but in production it will be something else (gor is your are interested). Just think of a process that doesn't end on its own (top,tail, etc.).

I suppose the end goal is to replicate production traffic patterns as close as possible. Why not just use production traffic? Of course omitting PII is mandatory.

Take a look at goreplay. https://github.com/buger/goreplay/wiki

Not OP, but that is the idea. I use this tool for it, as it is dead-simple to get running and fairly configurable: https://github.com/buger/goreplay

I'm assuming this breaks a ton more than just my project (https://github.com/locustio/locust/actions/runs/4687344723/jobs/8315803536)

If, like me, AGPL isn't your cup of tea, you can look at vegeta or locust which are both MIT.

locust if you can code

Agreed with a lot of the points here, like starting small with a single piece of your API, then slowly expanding your tests once you’re comfortable that you know what you’re doing.

Note that if you use the Locust framework to write your load tests in Python, it takes care of measuring and reporting the latency and throughput for you. It’s really nice.

For my application, to tune these parameters I used a load testing tool. I built a script using Locust.
