Indexes play a critical role in enhancing your database performance by facilitating faster query execution. Having the right indexes in place can speed up the process of fetching data from your underlying tables whereas having redundant indexes can hurt the performance negatively.
Performance Tuning
Generate millions of rows of test data for SQL Performance Analysis
Your application is bound to grow over a period of time. Sometimes it is critical to test your changes with a bigger workload than your current table size to identify any performance bottlenecks, well ahead of time. Leveraging automated tools to generate a workload for you to test your application makes your lives much easier.
Identifying Missing Indexes in SQL Server
Having an effective Database Indexing Strategy is a key to your application performance. When we think about optimizing SQL query performance, generally the first thing which comes to our mind are ‘Indexes’. And rightly so, because Indexes tremendously help in fetching your data faster from SQL Server.
Lock Escalations in SQL Server
“Lock Escalation” is an optimization technique used by SQL Server and it is basically how it handles locking for large updates. When SQL Server is going to modify a large number of rows – it is more efficient for the database engine to take fewer, larger locks (table lock) instead of dealing with a large number of individual locks (row locks).
