Nagios will normally send a notification when the service or host goes
from a soft state to a hard state.  When that happens depends mainly
on the max_check_attempts and retry_interval directives.  Only after
the last check attempt fails will Nagios send the notification.  If
you want immediate notification, set max_check_attempts to 1.  Take a
look and if you still can't find the problem, please find the relevant
host definition in your objects.cache file and post it here.

There are various things that can cause Nagios to run slowly.
Important metrics to check are host_check_latency and
service_check_latency - you will find those on the tactical overview
screen.  If either of those are more than 15 seconds or so I would
start investigating why.

Of course you could genuinely have a performance problem in your email
system...  That should be easy to check by sending an email from the
command-line on your Nagios server and checking it arrives reasonably
quickly.

hth,

Jim
