Regarding your ping check, it may be trying to perform reverse DNS
lookups and when this times out it always take time. Try fixing the DNS
if you can, or use check_icmp instead (the plugin must be setuid root).

Besides the plugin timeouts, you also have the Nagios check timeouts
(nagios.cfg) and, when running plugins trough NRPE or SSH, the
check_{nrpm,ssh} timeout.

Hope this helps,
