Shameless self-promotion: the homepage of plaintextsports.com is 5.2kb today [1], an in-progress WNBA game (4th quarter) is 11.2kb [2], and an extra inning MLB game is 8.8kb [3]. I wasn't aware of this size threshold, and I'm not at this level of optimization, but I'm always pleased to find more evidence of my playful claim that it's the "fastest website in the history of the internet".
