Avoiding SQL Server Performance Problem

SQL ServerSQL server is a complicated thing to the untrained eye. But then, for experts, an SQL server can be a piece of cake to handle. And, another but, though you have this long been running SQL server there are just additional things you should take into considerations in order to boost SQL performance.

And this consideration should include things that should be avoided. These here go to the developers and in the keen eye of the SQL consultants as well. For consulting for SQL server, one’s team can take this and try as much to learn from this.

A friend of mine had narrated this to me once; he has been in the SQL world for over ten years and had nearly experienced a thousand query problems and errors for the server. But then, as to his expertise, everything went well and right now he is still in the business. Now, what are these things you should be looking out for?

Overlooking the Clustered Indexes

Clustered indexes can add up a performance boost to your SQL server no matter how little that is. But then, clustered indexes can make a great difference in the process. This failure in the performance can occur right after there is an onslaught of a few million rows. The table becomes heavily fragmented and was now drawing on also performance from the process. The remedy here is to restructure and cluster your indexes.

Overlooking the AWE Memory Usage

So this is where some problems can stem up. Many experts and consulting teams fail configure or properly configure their AWE memory usage. This can result to poorly performing code. The answer here is to enable your SQL server to use more than the allotted 2GB of the RAM.

Not Knowing the Importance of Normalization

This is usually where developers often fail to give importance too. This feature would tune in performance and enhance it. The blunder happens and will be known only to some when there comes the performance problem from too much use of the database.

No Optimization Happened

Optimization can be the key or part of the key to ensure that problems with SQL performance will be minimized. This will help in poorly running codes and will be able to update your server.

Bandwidth Issues

So a constant update about execution status can result to a wasted network bandwidth. Why? Because it adds extra network operating cost. Only do what is needed and restrict things.

So while the things above were just a few of those things that should be discussed, still they may prove useful. Though lots of these aren’t secrets, but still lots of the experts tend to overlook some of these things in the process.

I just hope in the end that you can fairly materialize some tricks in order to enhance performance. That would mean your creativity and keen eye of details and what to do. Start checking out for failures and size up the SQL that you re running today.
