There are at least two ways to take Andrew's quoted text. One way is
that over time, Linux will do better than NetBSD (in the long haul,
which is how I first read the quoted line). The other way is that at
this point in time, if we look at datapoints beyond the right edge of
Andrew's graphs from last week, Linux does better than NetBSD. From
off-list discussion with Andrew, I am sure he means the second, not
Andrew's comments in another message, referring to a gradual drop-off
with increasign number of connections and suggesting kernel profiling
in that regime, to find the source of the gradual drop-off, also
support thet second reading.
Andrew can say more on this score if he chooses.
