Nagios monitoring limits: hosts and services

I'm starting to get complaints from our Operations group that the Nagios
web GUI is "getting slow".  This is on a version 1.x Nagios server.  The
server is monitoring 678 hosts and 3481 services organized in 29 host
groups.  Most checks are done on 5 minutes intervals.  I've gone over
all of the documented "tweaks" to improve performance.  The hardware
seems adequate and isn't starved for CPU; loads seem reasonable;
although the "Check Latency" under the "Performance Info" screen
continually creeps up - currently at Max. 23 seconds.

Time to load the "Status Overview" screen: 8,5,6,6 seconds
Time to load the "Status Summary" screen: 42,35 

I guess my first question is what do your uses expect in terms of
performance?
Am I missing the boat on something real basic here?
How many hosts/services do you manage per Nagios host?

Thanks in advance
