In this article, we will discuss how to read the SQL Server execution plan (query plan) with all aspects through an example, so we will gain some practical experience that helps to solve query performance issues. Interpreting query plans correctly is the first and major principle to troubleshoot query performance issues. When we try to find an answer to the “why is this query running slow?” question, the best starting point would be to analyze the query plan.

The SQL Server execution plan (query plan) is a set of instructions that describes which process steps are performed while a query is executed by the database engine. The query plans are generated by the query optimizer and its essential goal is to generate the most efficient (optimum) and economical query plan. Some query plans that are created by the query optimizer contain some interesting characteristics. In this article, we will go into details of these interesting query plans.

In this article, we will explore, how we can increase SQL Server performance with the help of the wait statistics. Wait statistics are one of the most important indicators to identify performance issues in SQL Server. When we want to troubleshoot any performance issue, at first we need to diagnose the problem correctly because correctly diagnosing problems help with half of the solution. Now, let’s learn wait statistics which helps to identify performance issues properly.

In this article, we will learn how to use Apache JMeter to perform a load test on SQL Server. This test type enables us to measure the application behaviors under specific conditions so that it enables us to observe a variety of resource consumptions (CPU, memory, latency, response times, etc) and it also helps to detect the performance bottlenecks. Database testing can help to find out and identify the problem when the database working under high workloads with multiple users. The database people can identify and fix the performance issues before publishing the database into the production through these tests.
