Since Monday, my script is seeing *average* response times ranging from 0.8 to 1.5 seconds from all Wikipedia pages that I sample, with 99% of calls served in less than 5 seconds. The only exception is the Recent Changes pages on the non-English Wikipedias, which take up to 4 seconds on average. (The ping roundtrip time alone from Sweden to San Diego is .2 secs, so the theoretical "room for improvement" is only 0.6 - 1.3 secs.)
