As a DBA you must have encountered a slow running application on SQL Server, but there are various factors that could be affecting the performance. If you find yourself in this situation, don't wait, pick up this book and start working towards improving performance of your SQL Server 2012. SQL Server 2012 Performance Tuning Cookbook is divided into three major parts -- Performance Monitoring, Performance Tuning, and Performance Management--that are mandatory to deal with performance in any capacity.
SQL Server 2012 Performance Tuning Cookbook offers a great way to manage performance with effective, concise, and practical recipes. You will learn how to diagnose performance issues, fix them, and take precaution to avoid common mistakes.
Each recipe given in this book is an individual task that will address different performance aspects to take your SQL Server's Performance to a higher level.
The first part of this book covers Monitoring with SQL Server Profiler, DTA, System statistical function, SPs with DBCC commands, Resource Monitor & Reliability, and Performance Monitor and Execution Plan.
The second part of the book offers Execution Plan, Dynamic Management Views, and Dynamic Management Functions, SQL Server Cache and Stored Procedure Recompilations, Indexes, Important ways to write effective TSQL, Statistics, Table and Index Partitioning, Advanced Query tuning with Query Hints and Plan Guide, Dealing with Locking, Blocking and Deadlocking and Configuring SQL Server for optimization to boost performance.
The third and final part gives you knowledge of performance management with help of Policy Based Management and Management with Resource Governor.

Who this book is written for
SQL Server 2012 Performance Tuning Cookbook is aimed at SQL Server Database Developers, DBAs, and Database Architects who are working in any capacity to achieve optimal performance. However, basic knowledge of SQL Server is expected, but professionals who want to get hands-on with performance tuning and have not worked on tuning the SQL Server for performance will find this book helpful.
system health using system statistical functions Monitoring SQL Server processes and sessions with system stored procedures Monitoring log space usage statistics with the DBCC SQLPERF command Introduction There are a few system statistical functions, stored procedures, and DBCC commands that can be useful while analysing performance-related issues. However, even though most of the statistical information that these commands provide can be retrieved by using dynamic management views
this recipe, to get log space usage statistics on all databases, we will use the DBCC SQLPERF command. Apart from retrieving log space usage statistics, the DBCC SQLPERF command is also used to reset wait and latch statistics. DBCC SQLPERF accepts one argument, LOGSPACE, when it is used to get log space usage statistics. However, it also accepts other arguments; they are used to reset the wait and latch statistics. Useful columns that the DBCC SQLPERF command returns for log space usage
to query execution. These DMVs and DMFs can be used to monitor statistics pertaining to the cached queries, execution plans, active connections/sessions, and currently running queries along with their execution plans. Index-specific DMVs and DMFs (sys.dm_db_index_* and sys.dm_db_missing_*): This category provides the statistics related to indexes. These DMVs and DMFs can be used to monitor and troubleshoot the performance of the indexes by finding missing indexes, unused indexes and examining
tables and columns cannot participate in a replication topology, and columns with large datatypes cannot participate in a columnstore index as well as in computed columns. To use DML statements, we have to disable columnstore indexes first, because the columnstore index is mainly designed for data warehousing purposes, where DML statements are not required. Chapter 10. Maintaining Indexes In this chapter we will cover: Finding fragmentation Playing with Fill Factor Enhancing index
value and those stored values are updated each time you change the value of the original column. Moreover, you can't use Computed Column names in INSERT and UPDATE statements. As it is already proved that an index plays an important role in performance, in the previous chapter, Chapter 9, Implementing Index, it is good to know whether it plays any significant role in all re-calculative values.
