Usability analysis of the Friendster Internet service, collaboratively created by the students of MIT course 6.171 in November 2003.´
Interesting factlet in the wrap-up section:
Nearly every student complained about the speed of Friendster. As a classical Web/RDBMS application it ought to be possible to make it fast at a reasonable cost. According to [this article], the programmers of Friendster rely on a cluster of 50 servers each running MySQL plus custom software that distributes updates across these peers, i.e., a given user is talking to Server #37, does an update to that server's local MySQL database, and that update is somehow later propagated out to the other 49 MySQL installations on the other 49 servers.
