Good idea but what happens if your connection to your ISP cannot be established 
for any number of reasons or your ISP is down. The reason why this is done is 
for redundancy if and when no other avenues of connection is possible, not for 
any other advantage such as speed and bandwidth. Pure and simple, just for 
redundancy.

I certainly have a lot to learn in that arena. When I dial my ISP, i usually
get speeds of wapping 19.2 speed. As you stated, i am consistently @ 28.8
when i dial in direct to my server. My thought that it would be a little
faster or @ least consistent speed( @ least if there were lots of traffic on
the isp). DSL is not available up here( a pretty isolated community in the
mountains). But, let me bounce what my thought was off of you and see if I
am correct if you don't mind. My performance increase would occur if:

I actually was retrieving data over the internet ( because that data only
traveled to my office pc, as opposed to all that data traveling across a
dial-up and I am using enterprise manager a lot).

Secondly, it would improve if I was downloading, because it also would only
be to downloading to the office machine.

Also, I thought there are scripts built into the pages being served that
would reduce performance some if they were being served to the dial-up pc as
opposed to just pixel changes.

I would see no real improvement( or limited) if:

I were changing the elements of the screens a lot( like watching video)
because it would be sending major pixel changes across my dial up(sound and
print jobs the same way).

Input is greatly appreciated.

Best Regards,
Chris

Chris,

I don't like to be the bearer of bad tidings but ... Internet speed
is - pure and simple - the speed of the slowest link. If you think
of any internet connection as:

The computer you are using -> LAN -> local internet server/router
-> line between your local facility and phone company 'central
office -> the rest of the phone company links between you and
your ISP (or in this case the 'office computer') -> all of the
modems/computers/routers there -> other "interim" stuff -> the web
backbone (ie. beyond your ISP but not all the way to the other end)
-> some other ISP on the other end -> its modems/computers/routers
-> the line between that ISP and the actual web server you are
connecting to's network -> whatever local modems/computers/routers/
ethernet connections they are using -> and -FINALLY- the computer
that is actually serving up the page(s) you want. (Some of these
links may or may not exist in your specific situation - others may
exist I have not listed ... it makes no difference. Why? Because
this is a "slowest link" scenario!)

We tend to think only of 'connect speed' ... but actually WWW
speed is a combination of all of the above - and is especially
sensitive to 'the weakest/slowest link'. And, regrettably, we
can't do anything to speed up what is outside of our control - so
anything beyond our local line speed is often left out of the
equation but DOES affect us and is why sometimes when you go from
a DSL to a T1 line you don't see any meaningful improvement in
surfing/download speed (for a specific site ... yes, T1 is faster
for most stuff and even "over all"). When you reread that paragraph
above and think about how many individual pieces of technology you
are using when you use the WWW to just do something as simple as
send a text email message ... well sometimes I just genuflect and
cross myself and say "I'm surprised this stuff works at all!" ...
much less how fast it actually is to download several MBs of a single
file from a truly busy server such as MicroSoft Windows update!

So ... back to your attempt ... in what you are doing the weakest
link is the line between your home computer and the company system.
That line will be - quite probably - SLOWER than just dialing up
to your ISP. Computer-Computer direct links often run at a MAX of
28,800 BITS per second! The truth is - just because the modems on
both ends are 56kb modems doesn't mean that the two computers will
talk that fast when using a computer-computer link. No matter how
fast the connection to your company's server is it will probably not
be 'faster than whatever direct dial-up to any ISP you are already
using' is ... because you are talking about using a phone line
connection which will never run faster than 53,300 (because the
phone company won't let it go faster than that) and when the biggest
factor controlling your phone line speed is the distance between you
and your "central office" (aka a "CO" by the phone company - which
is a phone company specifc computer somewhere in your neighborhood
and not necessarily in a building that has people in it and all that
stuff).

My suggestion is - nice idea but don't waste your time trying to
make it work. You won't find it is any faster than just dialing
up to your ISP. You are probably using a 2nd phone line for your
internet. And paying for both that line and your ISP. Just convert
that line to DSL - without a voice capability - and the DSL speed
will cost you, at most, about $10/month more than what you are already
paying for phone line PLUS the ISP charges.
