: Optimization and troubleshooting :

1. From slow-running queries to inefficient database setup, there could be number of reasons that your database isn't running as fast as you should like it to run. Having a poorly performing database translates to:

  • High page load times
  • High transaction commit time
  • High server usage (CPU, Memory, IO ....)
  • Frustrated visitors on your site!

DatabaseSkills understands how important it is for you to have a fully optimized database. That is why our expertise is available to troubleshoot performance problems with your database. Unlike traditional database administrators / developers, we are willing to go "under the hood" and look at the settings, the design, the structure, and anything else that could be standing in the way of optimal performance.

2. Just because your application works doesn't mean that it's running as efficiently as it could be.

Many application developers are unaware of exactly how hardware resources will be used to process their code, or how much cpu will be used to serve an application. In fact, most significant performance problems can be attributed to code or database design issues.

In many cases you can temporarily relieve these problems by purchasing more hardware; but at DatabaseSkills we will examine your application and database queries to target specific areas for optimization. Instead of throwing expensive hardware at the problem, we can help to pin-point your performance issues so that you can correct them in a targeted, cost-efficient fashion.
