Hi coders 👋. Hope you're all enjoying the series. Question: Which performance benchmarking tool do you use and or recommend? Cheers 😎

These Node JS Performance Optimizations videos are a real hidden gem. You deserve more views! Keep up the amazing work.

Awesome video. waiting for your next video.

Excellent!!

great videos man

I suggest the way how to increase a performance test quality - spin up a dedicated virtual machine (in some cloud) for your application (or spin up a dedicated stress-testing environment for your project, intended to be used only for the performance-tests), and a dedicated virtual machine (probably, more powerful) for the autocannon. By doing so your application will not be affected by the autocannon itself, and your testing condition will be 100% predictable. Well, not 100% predictable if you use Virtual machines, your results might depend on Virtualization and underlying host machine utilization. So, I suggest (and most of the time it is not cheap, unfortunately), spin up the dedicated server. One caveat to mention - your cloud provider might think that your performance tests is a DoS attack. In some situations, it is better to notify your hosting provider in advance about the traffic and purpose.

Man how are you now famous...Thank you very much for the information. Very few do that.

can we do this inside the docker container that runs the nodejs application so that we can do this in an isolated environment?

How to improve performance: Ditch express and use fastify

Hi - I would like to know why did you need to create the server with http instead using the express app as is? as in invoke the listen method on the express and not on http.

You are underrated, lots of good information in your videos, please don't stop making videos like this. but fastify is becoming a better alternative for express. not many good videos are out there, even matteo(founder of fastify) tweeted last week that there aren't enough videos on fastify, which is the root cause of it not growing, as most developers prefer videos. why don't you make videos on fastify?

Hi is there a way to do a performance test of a CPU extensive node app. The app is cluster app with child_process and worker thread with lot of blocking code.

whats your pc configuration? @bleeding code?

Protip: Don't log 404s unless you want a really easy way to DDoS your server/overload IO/fill your disk with logs.

Man, be more concise...
