w3wp process high cpu

In Linux, how does one view high CPU usage threads? in Linux, the top tool can display the average cpu usage (user, nice, system, idle, iowait, irq, softirq, etc ), the usage of each cpu is displayed. However, the cpu usage of each thread cannot be displayed. in Linux, how t

very large reduction, you run the computer will not feel the card. At the same time, hard disk life is also long. The second recruit: the frontier, reduce the QQ process priority If your computer configuration is not too high, QQ chat records are often cleaned, but also QQ occupy CPU high, how to do? Now the dual-c

you actually use a large number of group by statements in SQL statements, union queries will definitely increase the usage of mysql. Therefore, you need to optimize the SQL statement. The website should generate static websites as much as possible. Generally, for static websites with 4 W ip addresses, the mysql usage is almost 0. Therefore, this is a consideration for the programmer's experience. Improve mysql performance as much as possible (more than 20 best experiences on MySQL performance o

deliver to the customer. Reflect on the process of solving the problem, think that this analysis process has reusability, worth summarizing.1. Use the top command to see which process is consuming high CPUThe gateway process 14094 consumes up to 891%

large number of group by and other statements, union query, etc. will certainly increase the occupancy rate of MySQL. So you need to optimize the SQL statements, the site as far as possible to generate static, general 4W IP static Web site, MySQL occupancy rate of almost 0. So this is a consideration for the programmer's experience. Maximize MySQL Performance (best 20 + experience sharing for MySQL performance optimization) The following is a collection of articles by the cloud Habitat commun

Background: Performance monitoring shows that the CPU usage of a single core of the online server has reached 100%, which is caused by one of our core services. Thanks to the fact that our service processes are undertaken by multiple identical worker (thread) scheduling tasks, in addition to the high CPU usage, the service is not affected. The last time we found

In Linux, how does one view high CPU usage threads? in Linux, the top tool can display the average cpu usage (user, nice, system, idle, iowait, irq, softirq, etc .), the usage of each cpu is displayed. However, the cpu usage of each thread cannot be displayed. This may occur

replication, resulting in CPU utilization rate of resources is high. Solution: Clean the system memory and local hard drive with reliable anti-virus software, and turn on the system setup software to see if there are any abnormal startup procedures. Update anti-virus software and firewalls regularly, strengthen anti-virus awareness, master the correct anti-virus knowledge. 4, Control Panel-management tool
