Those times seem long for that number of hosts. In most cases (including
a system I'm looking at now with around 2100 hosts and 11,000 services
being monitored) the bottleneck's bandwidth more than the server on the
big pages like the service detail, but I haven't used a Nagios 1.x
system for quite some time.
Have you tried keeping your status data in RAM? I've seen some pretty
decent performance gains from doing that in other cases.
