Netli pumps up SSL performance
NetLightning service speeds secure traffic by as much as 70%, company says.
Network World, By Tim Greene: November 17, 2003
Web-acceleration service provider Netli is upgrading its support for Internet transactions protected by Secure Sockets Layer technology so they perform faster than before.
With a new service called NetLightning SSL-AT (SSL-Application and Transport), Netli says it can make SSL transactions up to 70% faster than could its previous SSL service, called NetLightning SSL-T.
Netli cites an example showing slightly less improvement: A user in San Jose without NetLightning would wait more than a minute to reach his calendar via Microsoft's Outlook Web Access on a server based in London. That measures the time between delivery of the main Outlook Web page and the time the calendar is displayed. Using NetlLightning SSL-T, the time drops to less than 40 seconds, and with NetLightning-AT that drops to less than 25 seconds, Netli says.
In another example, the average download time worldwide of the main Web page for electronics maker Tektronix in Beaverton, Ore., dropped from 2.5 seconds to 1 second after it bought the Netli service, says Larry Bunyard, director of Tektronix's Internet business group.
Tektronix says minimizing download times for customers is a top priority for the company, and it keeps track of how fast it takes to pull down its competitors' sites. The company considered using Akamai Technologies' service, which also speeds download times over the Internet. But Akamai's service is better-suited to speeding performance when many users request the same data, says Bunyard. Much of the data Tektronix's customers seek is large, diverse files containing product catalogs.
Akamai moves content to more servers or to servers close to requesters in response to spikes in demand for the same content, thereby reducing the hops the data makes over the Internet, says Peter Sevcik, president of NetForecast, a network technology consulting firm. NetLi's model, transporting traffic over the Internet between Netli points of presence using a streamlined, faster version of TCP, is better-suited to businesses using the Internet as Tektronix does - a way to speed access to a wide variety of bulky content and applications, Sevcik says.
Tektronix considered distributing Web servers of its own to regions of the world where delay was significant to reduce the distance data traveled. That required investing in hardware, distributing it to secure sites and keeping the content synched, Bunyard says. "The key for us is reliability, and the more elements you add, the more elements that are sure to fail," he says.
In addition to its new offering, Netli has added compression to its service, which reduces the number of bits it takes to send a given block of data. The Palo Alto company founded in 1999 has also set up new POPs in Seoul, South Korea, and Mumbai, India, bringing the total number of POPs to 15.
Netli charges $10,000 to $20,000 per month, per application, for Netlightning SSL-AT. The lower price is for using the Netli POPs in a single region, and the higher price is for global use.
