System: % processor queue length number of threads waiting for processing by the processor (the normal range is 1 ~ 3 times)3. Processor: % USER time occupied by non-kernel-level applications (such as sqlserver or anti-virus software)4. Processor: % interrupts

After the client is installed, it is intended to monitor the performance counters on the Windows side, primarily to monitor SQL Server-related counters. The online writing is not detailed enough, as the first to learn, or to find more information, the final Test success.The

I. Preface After the new installation of SQL Server 2005/2008, We need to configure SQL Server Based on the server's hardware and software facilities to achieve better performance. However, the default configuration is used in most cases. Ii. Configuration 1.

The impact of Tempdb on SQL Server performance optimization and tempdb Performance Optimization First, consolidate the basic knowledge of tempdb. Introduction: Tempdb is an important part of SQLServer, which is used to store temporary objects. Tempdb is an SQL

SQL There is no memory pressure on the Server. Conclusion: Memory is the most important resource of database system, the management of operating system and SQL Server is more complicated, from the value of above count value, it is basically able to infer whether SQL

Recommended threshold Value 90% Current Disk Queue Length AVG. Disk Queue Length (if you are using a RAID device, the%disk time counter can display a value greater than 100%.) If greater than 100%, AVG is used. Disk Queue Length counter determines the average number of system requests that are waiting for disk access No more than the number of disks 1.5~2 if the top two values are always high, consider upgrading the disk drive or moving some files to another disk or

SQL Server focuses on optimization of Stored Procedure performance, data compression, and page compression to improve IO performance (I ). Preface The SQL Server basic series is not over yet, And the last point is not written, and

Original: SQL Server performance Optimization nolock, greatly improve database query performanceThe company database grows with time, the data is more and more, the query speed is also more and more slow. Into the database to see a bit, hundreds of thousands of of the data, the query is really time-consuming.To improve the query
