Load Testing With k6: Finding the Bottleneck Under Real Load
Throwing real load at the system with k6 and reading how it scales. Firing over 25,000 requests at the link-open path, then cross-checking the k6 results against CloudWatch metrics to find the bottleneck. The numbers point straight at a figure seen many times in the series: the concurrency limit of 10, and show the system sheds excess load fast instead of collapsing.
