I am working on a personal project. It is not a great project that can receive real users, but it is just a side project, but I was thinking about how much traffic I could handle if users actually used my service. In the meantime, I signed up for this lecture, and in the beginning of the lecture, the basic concepts such as ‘throughput’ and ‘latency’ were well explained before the performance test, and from the middle of the lecture, I was able to directly perform the performance test using the Artillery tool, and I was able to check various indicators by applying it to my side project. I highly recommend it to those who need performance testing or want to get a taste of performance testing in a short period of time.
