cpu diagnostic tool

Previously, a device file collection tool was developed using Java Swing. Supports multiple devices to be collected at the same time, using one thread per device. At the same time collect more than one device information, found that the CPU occupancy rate actually reached 97%, and high. Obviously, such performance is intolerable.We know that with the tools JVISUALVM the JDK, you can see the execution of eac

First, prefaceIn recent times, there have been two problems with websites:1. Memory usage increases slightly until the server memory fills up.2. When you visit a page, the page responds too slowly and the CPU stays high.An initial estimate of memory growth may be due to the fact that there are unsaved resources that are taking up memory, and that the CPU is high probably because of the time-consuming operat

Tool for detecting CPU temperature in Ubuntu Now the weather is getting hotter. My laptop friends feel that the hands on the keyboard are getting hotter and hotter. Especially for Ubuntu Linux. We recommend a small tool for testing the temperature currently in use. It is a Chinese interface. Computer Temperature Monitor, which is available in the Ubuntu Softwar
