Performance Issue with large number of Virtual Log Files in SQL Server Transaction Log

SQL Server transaction log files have an internal structure called the Virtual Log File or VLF. When the number of VLFs grow out of control due to autogrowth the log can become fragmented and cause delay. In this tip we look at how to see how many VLFs exist as well as how this can be reduced to a more reasonable number.

Using Dynamic Management Objects to Monitor I/Os Against an Instance of SQL Server

To ensure that queries run as efficiently as possible, the database administrator needs to monitor performance to find inefficient queries. This article focuses on exploring how a DBA can monitor the I/Os against an instance of SQL Server, using Dynamic Management Objects, or more commonly know as Dynamic Management Views (DMVs) and Functions (DMFs).

Parallelism and Performance: Are You Getting Full Return on Your CPU Investment?

A closer look at CXPACKET wait type in SQL Server

If you have a server that has more than one CPU core, you may experience high values of CXPACKET wait types. This is typically due to queries that run in parallel and the real issue is to understand how different versions of a query can impact CXPACKET waits. In this tip we examine how changing a query can impact CXPACKET waits.

Built-In SQL Server Agent Performance Reports in SQL Server 2005

SQL Server 2005 includes a number of built-in reports to assist you in troubleshooting and measuring performance. In this tip I will cover the Built in SQL Server Performance Reports related to SQL Server Agent within SQL Server 2005.

Analyzing I/O Characteristics and Sizing Storage Systems for SQL Server Database Applications

Understanding how to analyze the characteristics of I/O patterns in the Microsoft® SQL Server® data management software and how they relate to a physical storage configuration is useful in determining deployment requirements for any given workload. A well-performing I/O subsystem is a critical component of any SQL Server application. I/O subsystems should be sized in the same manner as other hardware components such as memory and CPU. As workloads increase it is common to increase the number of CPUs and increase the amount of memory. Increasing disk resources is often necessary to achieve the right performance, even if there is already enough capacity to hold the data.
