The revamped site also relies on URL caching to store content in compressed formats with open-source Web Proxy caches running in front of some Web servers. And C&W's Footprint caching service lets MLB.com distribute its content geographically, too.

Meanwhile, MLB Advanced Media recently installed two additional NetScaler devices for the Gameday application and online polling, to use with tasks such as All-Star voting and other fan feedback. The extra boxes will let the organization split individual applications into modules among the Web servers for even more efficiency.

Shaffer says his group also is considering grid computing for the Web servers. Today those servers handle one or two tasks at a time, such as JSP processing and browser redirects. But the ability to share CPU power could boost performance even more for the ever-expanding Web site. With the site's Sun SunOne server farm mostly Netra 1125s and SPARC 4500s, MLB has already laid the groundwork for going grid, Shaffer says. "When we feel grid is production-ready, we may move to it," he says.
