During application maintenance for the customer, I noticed some performance problems under high load conditions. Theoretically, increasing the load on the application will reduce the performance, but I think the performance drop rate is much higher than the load increase. At the same time, I also found that, performance can be improved by changing the logic of the application. To learn more about this, we need to perform some performance analysis. At this time, we naturally need to use some perf
