4. Start the New Year with an Informix Database Performance Tune-up and Healthcheck

Our performance tuning is a scientific examination of your database server to identify bottlenecks and provide recommendations on how to get the best results from your system. We begin by setting up scripts on your system to monitor and collect statistics from your server, the operating system, CPU, memory, and disk utilization. A complete review of your Informix Database server will start you off to a better year.
