records without indexing does not take a lot of cpu time. It seems that the search for this table has a problem. Therefore, add an index to the _ mydata_key table based on the field keywords: mysql> ALTER TABLE `_mydata_key` ADD INDEX ( `keywords` ) After this index is created, the CPU immediately drops down, at 50% ~ Between 70%. Call show prosslist again, and the SQL call of website A rarely appears in t

backgroundThrough performance monitoring, it is found that a core occupancy rate of the on-line server CPU has reached 100%, and is caused by one of our key services. Fortunately, because our service processes are assumed by multiple identical worker (thread) schedules, there is no impact on services other than high CPU usage. With the last time we found the one

This article is guided by: The trigger causes deadlock, the job is many and frequent, the use of the middle table, the large number of cursors, the design of the index is unreasonable, the transaction operation is frequent, the SQL statement design is unreasonable, will cause the query inefficient, affect the performance of the server. We can use SQL Server's own profiling Trace tool SQL Profiler to analyze the source of problems caused by database de

Knowing the server CPU model, how do we view the server CPU cores and the number of threads in the server?Steps:Right-click the taskbar at the bottom of your screen. A menu will pop up.In the menu, click "Start Task Manager" with the left mouse button.Click the "Performance"

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.
