Twitter Seeing 6 Billion API Calls Per Day, 70K Per Second

Last week, Twitter engineer Raffi Krikorian presented a number of new stats about the microblogging service as part of a recruiting talk at UC Berkeley. One interesting stat involves the number of API calls that the site is seeing: Krikorian says that Twitter is seeing 6 billion API calls per day, or 70,000 per second. That's more than double the amount (3 billion API calls) that Twitter was seeing in April, according to the Programmable Web.

Some of the stats, including the fact that Twitter is seeing 90 million Tweets per day, we also heard at Twitter's news event this past week. Krikorian delved into the amount of data storage each Tweet includes in terms of text (200 bytes for 140 characters). Twitter is seeing 800 Tweets per second, or 12GBs of Twitter text. And Twitter generates 8 terabytes of data per day (or 80 MB per second), whereas the New York Stock Exchange creates 1 terabyte of data per day.
