java code analysis tools

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

During the maintenance of the application to the customer, I noticed some performance issues under high load. In theory, increasing the load on the application can degrade performance ratios. However, I think the rate of performance degradation is much higher than the load. I also found that performance can be improved by changing the logic of the application, or even reaching the limit. In order to understand this in more detail, we need to do some performance

More than once, we all had the idea of trying to find out what was going on in the bottom of a running program. This need may be due to slow service, Java Virtual Machine (JVM) crashes, hangs, deadlocks, frequent JVM pauses, sudden or persistent high CPU usage, and even terrible memory overflows (oome). The good news is that there are a number of tools available to help you get the different parameters of t
