New author Koby Biller discusses some of the impacts that it could have and has a free tool for download that can help you determine how fragmented your disk truly is. http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/performancemonitoringbyinternalfragmentationmeasur/2014/2005/08/16http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/performancemonitoringbyinternalfragmentationmeasur/2014/One of the best ways to reduce the load on your server and increase application responsiveness is to reduce the number of "round trips" your application makes. This article by Andy Warren shows you a few ways to increase your performance by reducing round trips. http://www.sqlservercentral.com/articles/Performance+Tuning/roundtrips/586/2005/07/15http://www.sqlservercentral.com/articles/Performance+Tuning/roundtrips/586/As Chris points out, in most applications these days you end up having to go with optimistic locking, which presents a few challenges. Chris works through the list of options. If you're building web/disconnected apps and need anything besides last update wins, this one is for you. http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/dealingwithchangingdata/1233/2003/12/19http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/dealingwithchangingdata/1233/Part two in the Introduction to ADO series, this beginner level article shows how to open a recordset, how to add and edit records, and touches lightly on how to select the best cursor type and locking mode. Good code samples help you get started fast! http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/introductiontoadopart2recordsets/529/2003/11/28http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/introductiontoadopart2recordsets/529/Another new author! Gheorge shares some ideas about importing event logs and using OLAP to analyze the results. Not a bad idea at all. How many of use OLAP as often as we should? Read the article, see if it's something you want to try - and let Gheorge know what you think! http://www.sqlservercentral.com/articles/Administering/importingandanalyzingeventlogs/997/2003/05/28http://www.sqlservercentral.com/articles/Administering/importingandanalyzingeventlogs/997/Programmers can most commonly relate to interface-based programming in their programming language. This is harder to accomplish in SQL Server though. In this article by Chris Cubley, he shows you how to build interfaced-based SQL. http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/sql_interface_final/732/2002/07/19http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/sql_interface_final/732/This week Andy continues his series on how to reduce the number of round trips to the server by looking at some things you can easily add to your applications without a lot of rearchitecting. http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/reducingroundtripspart3/621/2002/03/11http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/reducingroundtripspart3/621/Architectural choices for data access affect performance, scalability, maintainability, and usability. This article focuses on the performance aspects of these choices by comparing relative performance of various data access techniques, including Microsoft® ADO.NET Command, DataReader, DataSet, and XML Reader in common application scenarios with a Microsoft SQL Server™ 2000 database.http://www.sqlservercentral.com/redirect/articles/620/2002/03/01http://www.sqlservercentral.com/redirect/articles/620/Last week Andy started a discussion of the various ways you can reduce the number of round trips to the server. This week he continues by looking at a method he used recently to do client side caching of data to eliminate the round trip altogether. Gotta read it! http://www.sqlservercentral.com/articles/Performance+Tuning/reducingroundtripspart2/588/2002/02/06http://www.sqlservercentral.com/articles/Performance+Tuning/reducingroundtripspart2/588/One of the best ways to reduce the load on your server and increase application responsiveness is to reduce the number of "round trips" your application makes.

Since session state can't be shared across a Web farm with Internet Information Services 5.0, a custom solution is required. One such solution using a tool called the session manager is described here. http://www.sqlservercentral.com/redirect/articles/244/2001/07/06http://www.sqlservercentral.com/redirect/articles/244/
