Testing backend application performance

This lecture is a ray of light for those who want to experience large-scale traffic but cannot. What on earth is the experience of handling large-scale traffic that is considered important in service companies? Or, you can experience it if you go to a service company, but you need to know it to go to a service company. I think this lecture is suitable for those who think, "What should a newbie like me do?" I think it is better because the lecture is set up so that you can see some functions that are not provided if you follow the current Artillery document. A few days ago, I remember an anecdote where a cell manager of a certain company was so well-versed in legacy that he gathered his team members and said, "Now, press F5 to refresh!" and said, "Let's do a traffic test!" I recommend this lecture because I think it can encompass even experienced people who do not have the concept of stress testing.

During the technology review process prior to a new project, we were able to quickly perform performance tests without separately setting up nGrinder or JMeter. This saved us time building the test infrastructure.

I'm actually working on a personal project. As the instructor said at the beginning of the lecture, I created an API, but I had doubts about how well my API could perform. That's why this lecture was even more touching, and I think I was able to take my first step toward performance testing easily through this lecture! And I realized that it's more developer-like to say more specific things like 'latency' and 'throughput' instead of just using the vague word 'performance' on my resume! I also liked that I could quickly review my knowledge about the operating system, and I think it was even more stimulating because he gave me gentle advice(?) that hit me in the face every now and then. ㅎㅎ

Thank you for the great lecture! However, the sound seems to be very low. That's a bit inconvenient - would it be possible to adjust the sound much louder??

It's not a lengthy lecture, but it helps you easily understand performance testing. It lays the groundwork for you to study performance testing on your own.

It helps that you calmly explained the background knowledge first.

I've gained a broad understanding of performance testing through the lecture. Based on this lecture and the next one, I will try to apply it to my personal project.

The well-organized lecture materials and explanations are excellent for understanding. I initially took this course because I thought it was important to improve and develop while enhancing actual projects, and I am satisfied! I will definitely listen to more in the future :)
