The average web page is now more than 1 megabyte (MB). … To put things in perspective: [last December], the average page was 965 KB. That’s 8 percent growth in just four months. Doesn’t sound like much? Then consider this: Back when the HTTP Archive started tracking page stats in November 2010, a mere 18 months ago, the average page was an already hefty 702 KB. Pages today are almost 50 percent bigger than that. If pages continue to grow at this rate, the average page will hit 2 MB by 2015.
How it can affect you:
Not only does a 1 MB page take forever to load, it can also deliver a nasty case of sticker shock when you get your phone bill. To give you a for-instance, earlier this month I was traveling in Europe. Before I left home, I bought 25 MB of data from my provider for $100. In other words, I’m paying $4 per page.
