The Problem: Low Productivity
What can you do when your Web application is mysteriously slow? How do you determine why your internal users are experiencing delays waiting for Internet Explorer to load the page? Is it network congestion? Is it an application server performing poorly? Is it the database server? Or is it just a momentary spike in your Web site visits?

Commercial Web sites today are dynamic, involving multiple technical components. Modern Web-based applications typically involve diverse platforms—firewalls, load balancers, Web servers, application servers, and database servers.

The Solution: Data-driven Performance Tuning
Isolating and resolving performance issues—in a multi-tiered application—requires collective IT skills. Network Architects offers valuable application, network, server, and database insights through its process of data-driven performance tuning. We deploy your application in a customized lab designed to extract definitive performance data. The data is then analyzed, summarized, and clearly presented in an executive report with representative graphs.
