Well, then this sounds like it might be a network problem of some sort,
despite the low ping times from your house.

Unfortunately, there's no good formula to figure out the appropriate value
for this field. Load testing is the only way to get the right value for
this, and the old Allaire recommendations (2-3x the number of processors)
are bunk.

The performance difference with this, as with any other CF configuration
option, may not be apparent unless under load - which of course is generally
when performance differences matter most.

I'd try to go through a process of elimination. What happens if you request
a regular HTML page from that server? What happens if you request an HTML
page on another server on the intranet from home? Are there any proxy
servers between home and the intranet? Does your firewall or proxy server
filter application content? As Cameron points out, if you have a good
network administrator, that person might be able to help you with the
general diagnostics, but otherwise, you're on your own.
