Possibly.  But I suspect not.

I have half a dozen sites Dreamhosted and delays like that were never a

I have had them running from sqlite3 rather than mysql, with and without
 Passenger.  I've had other problems but never unacceptable delays.

If this is shared hosting then you may be fighting a very basic problem
with multi-user machines.  You've been swapped out and the scheduler has
to swap you back in, and all the priority issues that go with that.

If you have a virtual machine there is the analogue of that at the
virtual layer.

Yes, I know tests show yamma yamma, but in reality the dominant thing is
that its the first 'wake-up' that is critical.

Its an operating system scheduling issue.

I'd suggest that you have some kind of CRON-scheduled 'tickler' that
does just enough to keep a bit of your process alive and awake but
doesn't produce such a heavy load that it impacts others.

Objects in calendar are closer than they appear.
