More bandwidth does NOT equal better app performance

Surprise! Bandwidth won’t fix your slow applications

The stats are in: More bandwidth does not fix application performance problems, according to KillerApps 2013 – a recent Vanson Bourne survey of 650 US and European IT decision-makers.

Respondents were asked if they added bandwidth in the past year, as well as whether they encountered an increase in application performance issues. As it turns out, 92% of U.S. companies are adding bandwidth by at least 10% per annum. In tandem, 69% of U.S. organizations are experiencing a frequency of application latency or non-responsiveness. Of those experiencing more application slowness, business critical apps (especially CRM, ERP, UC and collaboration systems) are impacted more frequently than ever.

So what’s missing? If bandwidth is being added, shouldn’t application performance issues decrease? The answer is “only somewhat.” If organizations add more bandwidth without any application control, it won’t stop one application from usurping bandwidth from a more-important application traversing the network. Solving application problems is not just about adding more bandwidth; it’s about adding network traffic management and traffic prioritization via quality of service (QoS), said TRAC Research President Bojan Simic.

Monitoring user experience for VoIP and collaborative apps is a good way to measure application performance,” Simic added. Not only is it important to control your applications, he said it’s important to have the proper metrics for measuring such application performance.

Let’s also not forget that WAN optimization controllers (WOCs) and application delivery controllers (ADCs) are proven winners at accelerating app performance. So before you add more bandwidth to your network — consider better network metrics, a QoS strategy and a WOC or ADC to better the application performance experience for your users.
