w3wp process high cpu usage

　　Cause 1. When the machine slows down, the first thing we think of course is task Manager, to see exactly which program accounted for a higher proportion, if it is a large program that can be forgiven, in the shutdown of the program as long as the CPU normal, then there is no problem; if not, then you should see what the program is, When you don't know what the process is, go to Google or Baidu search. So

Under Linux, the top tool can display the average CPU utilization (USER,NICE,SYSTEM,IDLE,IOWAIT,IRQ,SOFTIRQ,ETC.), which shows the utilization of each CPU. However, this situation may occur when the CPU utilization of each thread cannot be displayed, and the total CPU utilization is

two-byte alignment. By default, the common GCC compiler uses 4-byte align, which ensures that the first address of the thread lock attribute variable is a multiple of 4, when m68k is used for compilation, the _ align member cannot ensure that the first address of the thread lock attribute variable is a multiple of 4 (actually a multiple of 2 ).3.2.3 parameter error asking what causes high CPU

, especially when new custom types are added, all consumers are upgraded as much as possible, but when the consuming side is too high, the scenario is too expensive and unfriendly Improved serializerfactory, caching of reflection failures and avoidance of repeated reflections Issue for Dubbo, but it's not going to work out. ConclusionHession The default deserialization implementation satisfies the following 2-point condition, which result

It is found that the web server is abnormal in the monitoring, and the cpu and load will suddenly increase, and then it will return to normal in 10 minutes. Ssh connection, several php-cgi processes use 100% cpu. At that time, I suspected that some programs were not written, so I informed the development team to check them. As you can see, as the number of visits increases, several web servers found abnorma
