I came across this interesing interview with Mike Davidson of ESPN. ESPN recently redesigned their web sites and the interview goes into some detail about the process. Basically they've achieved significant reductions in bandwidth as a result of removing tables from all their pages.
I found the following information interesting:
Our traffic fluctuates with popular sports being in or out of season, but throughout the year, we get anywhere from about 1 to 1.3 billion page views per month. This is for all ESPN-owned sites. For just our site on the ESPN.com domain, we average anywhere from about a half a billion to 950 million page views per month. |
For the month before our redesign, we calculated that 97.44% of our users were using standards-compliant browsers (IE 5+, Netscape 6+, Mozilla, Opera 6+, Safari, Chimera, and Konqueror), and the rest were either non-detectable or using non-compliant browsers. The only substantial groups among the non-compliant browsers were IE 4.x at 1.32% and Netscape 4.x at 1.17%. The other .05% of our users were either undetectable or were using obscure or masked user agents.
