While looking through the server's properties, I came across a setting that corresponds to the latency issues we are seeing. Under System Resources there is "Time to wait between requests:". The help for this value sounds like it keeps the connection alive for this value.

That's right.

This value defaulted to 5 minutes, which was exactly the time I noticed in my testing. If I change this value to something greater than 5 minutes, the latency corresponds to this value. Is there any harm to setting this value to something like 4 hours?

You can try that, but be aware that what will happen is Apache will
basically hold a job in memory for KeepAliveTimeout seconds. That is,
right now, if you have 10 people using the intranet, and they all go off
to a meeting, their 10 HTTP server jobs will disconnect and return
resources back to the available pool in 5 minutes. Changing that to 4
hours will mean that those 10 jobs will hang around for 4 hours. That
may be what you're after, but it sounds counter-intuitive to me.

Is 'Allow persistent connections' Enabled or Disabled? (This is
KeepAlive in the Apache ini file).

I'm also thinking of changing the value of "Maximum requests per connection:" to unlimited. This server only services our intranet, so I can't see any harm in changing either value. Testing this change in our test environment didn't show any issues.

Try it for a day - it'll be one more data point. But if I can give some
advice: Change only one thing at a time. That way you'll have a better
feel for what setting has which effect.
