Is there smaller latency? As an American end-user on a commercial ISP,
my ping times to U.S.-based sites are not consistently lower than my
ping times to Europe-based sites, and some testing from European shell
accounts I have access to shows the same in reverse. In particular, it
seems the from the UK, ping times to the US are lower than to many parts
of continental Europe, and from Japan, ping times to the US are again
lower than to many other parts of Asia.
In either case, the transoceanic round-trip transmission times of
~80-150ms are dominated by Wikipedia's response time, which seems to be
measured in seconds rather than milliseconds. (I certainly notice that
browsing German newspapers from the US is much faster than browsing
Wikipedia from the US, geographic location notwithstanding.)
