AMP is fastest. It's not really possible to directly compare, because PB and Foolscap respectively have more features, but compare here: http://speed.twistedmatrix.com/timeline/?exe=2%2C4&base=none&ben=pb&env=d3&revs=200 and http://speed.twistedmatrix.com/timeline/?exe=2%2C4&base=none&ben=amp&env=d3&revs=200 You're of course welcome to contribute optimizations to PB :). -glyph
