Under the above configuration, Tomcat occupies 50-60% of the CPU. The performance is ok and the return speed is relatively low.The CPU usage remains the same, or even slightly increases, while the return speed of the slow ones increases. Theoretically, with the increase of CPU, the processing speed will be faster, while the return speed should be reduced, which is very abnormal. Could you help analyze the problem zhan...@51tuiyi.com
