They say technology is useless unless you have a killer app to make the day to day usage easier. But what happens when applications usage degrade due to external factors. Here's a good article where some tips, tricks and technologies that help
boost up application performance are highlighted by industry experts. One aspect that's always not included in amplifying the performance is the WAN side. Even with T1 or OC3 lines, latency could sometimes happen and adding good application aware hardware like those from Packeteer Inc could be very useful to keep users cool."Our network is scattered across the country with 82 field offices and 10 regional locations. Our field offices don't have local servers, and they had pretty slow lines," says Chris Finucane, CTO for the U.S. Department of Health and Human Services, Office of Inspector General in Washington, D.C. "We optimized the network and upgraded all our links to T-1 lines, and the field offices didn't notice a huge difference. That's when we realized bandwidth can't be everything and we needed to investigate other means to improve application performance."
Finucane's challenge is not unique, according to industry watchers who say today's increasingly complex applications simply aren't designed to run smoothly across large distributed networks that support branch, remote and mobile workers. That has network executives scrambling to invest in new technologies - such as application acceleration and WAN optimization tools - and others working with system administrators and application developers to tweak internal servers and fine-tune application code. We spoke with a handful of network professionals and industry analysts to get their advice on how to boost application performance across a network.
