High Call Volume SQL Server Applications on NUMA Systems

One of the most difficult database operations to scale-up on high-end server systems is the network call. In fact, without special precautions, a high call volume database application can have severe negative scaling on large systems. It is suspected that this problem is more pronounced on NUMA systems than basic SMP systems. A NUMA system with 16 processors can have significantly lower throughput capability than an otherwise comparable 4-way SMP system.

Index Creation Guidelines

The Steps to monitoring greatness

SQL Server Profiler can correlate Microsoft Windows System Monitor (Performance Monitor in Windows NT 4.0) counters with SQL Server or SQL Server 2005 Analysis Services (SSAS) events. Windows System Monitor logs system activity for specified counters in performance logs. The first thing to remember is in order to have correlating information you need to obviously be in sync - in other words you must start the perfmon trace and profiler trace at the same time or else they won't match up.

Database Geek of the Week - Gary Mallow

Database geeks are all around us. I met Gary Mallow on the email list of a cycling group run by a local church. After some conversation, I discovered that he is a director of a group of developers who build applications, sometimes using .NET and often using Oracle as a database. Like me, Gary is not entirely comfortable with his ability as a UI developer, and so finds database work a good fit.
