The highest Tweets per second #SuperBowl peak came at the end of the game: 12,233. 2nd highest was during Madonna’s performance: 10,245.

What impresses me about this number is that we’ve blown way past measuring tweets in milliseconds, which is the measure I most associate with Internet communications. A decent ping latency is 100 ms or less; this pace of tweets means Twitter is processing them at a rate of 0.082 ms each.
