I'm suspicious of that actimeo=0; it can cause massive slowdowns in
one of the four cases of which is client vs server vs whether you're
pushing or pulling.  (I can forward details if anyone cares.)

Try actimeo=1 instead.  You'll be within 1 second of up-to-date,
without the problems.  No idea if that's actually your problem
here, but worth trying.
