I do not know which John you are addressing this to, but LINUX is an 
area where I am close to being a novice.  The simple things that I do 
not know how to do with LINUX exceeds the more technical things that I do.

That said, most of the time that I have seen a network related slowdown 
issue is a problem in the DNS resolution and local hosts files.

This can cause delays as the each DNS that is either not functional or 
returning stale values must time out before the next DNS in the list is 
tried.

On my systems it usually means that the ISP's DNS servers assigns to me 
have changed, which happens about every 2 years.

Locally I use one of my OpenVMS systems as a caching DNS that only sends 
requests it can not resolve to the ISP's DNS.  This means that for the 
sites that I visit a lot, I do not usually have delays in resolving the 
I.P. address.

The downside is that I have never bothered to set up a script to verify 
that the DNS forwarding bind entries are up to date.  So periodically I 
have to make a tweak.
