I would try to see if the ISP/Carrier may be intentionally or
inadvertantly throttling traffic of this type. The fact that the users
aren't (didn't) complain about regular performance with Web Browsing etc
makes me think its not amount of bandwidth but the type. It can be
really difficult to get to the engineer that can answer this questions.
Have you isolated the slow performance to upload or download speed. OR
with emails of a certain size or greater?
Heres some recent reports about throttling - although its related to Inet
traffic and not VPN which should(?) be exempt
Comcast Traffic Shaping Impacts Gnutella, Lotus Notes?
The Electronic Frontier Foundation joins the Associated Press (and
everyone else) in confirming Comcast's traffic shaping practices,
something our readers have been reporting for months. The EFF's tests show
that in addition to throttling BitTorrent traffic, Comcast's traffic
shaping (using forged TCP packets with the RST (reset) flag set) is also
interfering with Gnutella and Lotus Notes. The EFF opines on why Comcast's
practices set a dangerous precedent:

When they bring their laptops into the office, local performance is fine.
We did enable network compression on the server and on one user's laptop,
unfortunately we have no tools to gauge connection performance so we can't
say that it improved his connection -- we only hear that it didn't make
any difference.
I'll look into creating local replicas, try it on one user and see what
the reaction is.
Another comment I've heard from a couple people is that when their laptop
has been sitting idle with the Notes client open, it takes a while to
reconnect or re-establish the session. Short of lengthening the session
time-out -- any other settings that would impact this ?
Thanks for the input...

Re: remote performance suggestions needed
If the internal performance is fine, then this is definitely something
network-related. If these are laptops, have them bring them into the
network
and see how they perform. If they're desktops, then there could be some
stuff running on them (spyware) to cause it to be slow.
Is network compression enabled on the Domino Server's port as well as the
Notes clients? This could help some for sure - especially if you set them
up
with local replicas and have them work off of those copies when at home.
