This article describes how to handle a performance issue that database applications may experience when using SQL Server: slow performance of a specific query or group of queries. The following methodology will help you narrow down the cause of the slow queries issue and direct you towards resolut...
RUNNING: Queries can be slow because they're running (executing) for a long time. In other words, these queries are actively using CPU resources. A query can be running for some time and waiting for some time in its lifetime (duration). However, your focus is to determine which is the...
One of the first checks to perform when you are experiencing slow query execution times is an index analysis. If you are investigating a single query, you can use thePerform Index Analysisoption in SQL Query Analyzer; if you have a SQL Profiler trace of a large workload, you can use the...
For instance, a slow running SQL query can cause a flow to slow down while it waits for the query execution to complete.Cause 2: The connector you use slows down your flow as a service protection mechanismFor example, the SharePoint connector caps actions at 600 per minute. A single...
SQL Profiler SQL Profiler is a powerful tool when troubleshooting your SQL Server 7.0, or later, application performance. SQL Profiler allows you to easily capture all the events that are occurring on the server under a typical load, and it provides information about them. Using SQL Profiler in...

Firstly, define the level of reader thread latency by running below query in Publisher server. sp_replcounters GO The above shows reader thread replicating on average 115 transactions per second and more than 7.5mln transactions are waiting to be replicated to the distri...
The SQL Profiler trace captures the activity on the computer running SQL Server. You can use this information to identify slow running queries and non-optimal execution plans. Additionally, SQL Profiler documents the series of events that occur before the performance problem and helps to identify it...
