iis worker process high cpu usage

Take the hbase benchmark to analyze which threads use the higher CPU, the environment is Linux, the benchmark command:HBase org.apache.hadoop.hbase.PerformanceEvaluation--rows=500000--nomapred--presplit=5--writetowal=true Randomwrite 5First look at the process and thread ID that consumes the highest CPU and execute the command:[Email protected] logs]$ PS Hh-eo pi

SQL Server checks CPU usage. At noon today, a friend asked me to help him check the database. The operating system is Windows2008R2, the database is SQL2008R264-bit 64 GB memory, and the 16-core CPU hardware configuration is still relatively high, he said that the server is running Kingdee K3 software, and there are mu

Use the top command to view the CPU-high PID# according to the top command, the dis

How to locate Java threads with high CPU usageTools:1Jstack:jstack is used to print the Java stack information for a given Java process ID or core file or remote Debugging service, if it is on a 64-bit machine, you need to specify the option "-j-d64", The Jstack usage of Windows only supports the following way. pidsta

　What is CPU usage? CPU usage is actually the CPU resource that your program runs on, indicating that your machine is running a program at some point in time. The higher the usage rate, the more your machine runs a lot of program

After php encryption is put into the server apache occupies a high cpu. after php encryption is put into the server apache occupies a high cpu, it is easy to reach 100% local encryption program test no problem, mainly Internet, once encrypted, the cpu

Operating Win7 Pure version of the system encountered a sudden high CPU usage and suddenly become low, seriously slowing down the system running speed, but also led to computer fever, if a long time, the loss of computer hard disk is very large, why this situation? Many users do not know the CPU

　　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

The last few days to update the program, testing the function, found that the application login is very slow, thought to be a problem with the application, but wait for a long time after the discovery of the application login is OK. Check the application log and discover that the data pool is full and cannot create more connections. Then quickly log in to the database check,1, top view found that the MySQL process
