30 concurrent requests at 1 or 2 minute intervals?  This seems weird,
as I would expect it to be more or less randomly distributed over that
interval.  Does this happen at the top of each minute?

If what you observe is true, the only situation I can think of that
would cause this is a bunch of POP3 fetch clients running as a cron job
synchronized to a minute grid (i.e seconds=0).
