I was working on one of my side projects last week and decided to stress test it a bit. I tried out LoadView to see how it would handle increased traffic, and honestly, it was quite revealing. My API started to slow down much sooner than I expected, and I discovered some database queries that were less efficient than I had thought.
This got me wondering: do you all conduct load tests during development, or do you wait until there's actual traffic before tackling that issue? It seems like many of us assume things will work smoothly, but that's often not the case. What tools or methods do you prefer for realistic performance testing?

Depends on the load and environment, but it's super generalized to say load testing is a must for all projects!
Honestly, I beg my team to do load testing, but they usually wait until production. It's a bit of a disaster waiting to happen, haha!
Haha, I get that! But this isn't an ad—just sharing a moment that was super eye-opening for me.
I think running load tests during development is crucial instead of waiting for real traffic. Even a simple script with k6, Locust, or JMeter can help you catch slow database queries or inefficient algorithms. You don't need to simulate thousands of users to find bottlenecks; even a few hundred connections can reveal limitations. Monitoring CPU and memory during tests can provide key insights for optimization!
That actually sounds pretty insightful!
I usually do load testing when I have a specific load expectation. I've experimented with a few cloud services and local tools like Oha, but I haven't settled on a favorite yet.
Can you share more details about what you've tried? Would love to hear your thoughts!
I really enjoy using k6.js for load testing. It's straightforward and effective!
Why is it an issue to wait until production for load testing? I'm used to this approach because production servers often have higher specs, making any staging optimizations unnecessary. Just curious about other perspectives!
