Fixing the Most Common SQL Server Performance Roadblocks

SQL ServerSQL Server is one of the most widely used database management systems in the world, and countless businesses depend on it. It is well known for its speed and reliability, but that doesn’t mean it’s immune to performance issues. If your SQL Server has slowed to a crawl recently, what should you do to fix it?

When in doubt, you should always consult a professional database analyst for troubleshooting and SQL Server support. It’s critical to solve performance issues early on, since they hamper productivity.

But if you want to try detecting the problem yourself, then here are a few common causes.

1. Out of date version – A surprising number of companies still run SQL Server 2000 or 2005, which are both no longer under development. These are horribly outdated, and simply cannot keep up with the demands of a modern workplace. You will likely see a huge performance increase once you update to a newer version.

2. Lack of memory – Given how resource-intensive SQL Server can be, it’s important to have the right hardware. For instance, the 2008 R2 Standard Edition can make use of up to 64 GB of memory; upgrading to this much should be a priority, if you don’t have it yet. You may also want to check if there are any notable competing processes that take up all the resources.

3. Architectural flaws – When hardware isn’t the problem, but the server still slows down when there are too many users, it may be a coding failure or architectural flaws. This is more difficult to pinpoint, but a common sign is excessive blocking of queries, caused by other operations.

Keep in mind, many persistent SQL Server problems require a deep understanding of the software and plenty of hands-on experience to correct. If you don’t have an in-house DBA to take care of this, hiring a consultancy is the next best thing.
