We were pretty pleased—until we noticed that DrProject had slowed down a lot after we introduced it. An undergraduate student named Billy Chun looked into the problem over the summer, and discovered that Plex was re-generating the parser every time it was called. More specifically, Plex was spending 1.9 seconds translating a nondeterministic finite state automaton (NFA) into its deterministic equivalent (a DFA) each time DrProject rendered a wiki page.
