Azure SQL Performance Tuning - A Guide

Welcome to the tutorial. This page focuses on optimizing your Azure SQL Server performance.

Key Performance Indicators (KPIs)

We'll examine key metrics:

Analyzing the Query - The Problem

Let's look at a typical scenario: A slow query impacting key performance indicators. It’s likely due to inefficient queries...

Example Query

This query is taking too long. It's consuming excessive resources.

Analyzing the Connection Pool

Insufficient connection pool size. More client connections are needed to keep the database responsive.

Without sufficient connections, your application might experience slowdowns.

Analyzing Index Usage

Lack of appropriate indexes leads to full table scans, dramatically slowing down queries.

Without well-optimized indexes, the database spends more time scanning the data instead of processing it.

Monitoring - Database Metrics

Monitoring tools are essential. We will use Azure Monitor to track...

- CPU Utilization: High CPU indicates potential bottlenecks.

- Memory Usage: Low memory can cause performance issues.

- Disk I/O: High disk I/O slows down the database.

- Query Execution Time: Directly track the time queries take.
