I concur with Zait. Your data supplier, broker and local equipment are far
more important than the DSL or Cable provider. Nowadays the actual
throughput from Cable or DSL is sufficient and somewhat similar. For
example, look at the actual DSL throughput shown at
http://reviews.cnet.com/7020-9032_7-0.html?tag=bbw
<http://reviews.cnet.com/7020-9032_7-0.html?tag=bbw&ac=&filter=9031&action=G
o%21> &ac=&filter=9031&action=Go%21. The numbers aren't all that different
from the actual Cable throughput shown at
http://reviews.cnet.com/7020-9032_7-0.html?tag=bbw. Cable providers
advertise big numbers but their actual throughput is usually far less.
National average Cable throughput averages over 2000 kbps but in many
localities providers such as Comcast are running at less than 1000 kbps.
Quite often even those paying the extra fee to get an advertised 6000 kbps
are often getting actual throughput of less than half that much.
An excerpt from a recent Comcast user's email is typical in some parts of
the country. "Hello,
I recently had HSI by comcast installed in my apt. on the 12th of oct. Since
then I've had nothing but issues with it. I've talked to techs on the phone
as well as having one come out. They ping me and say "everything seems ok"
but it's not. I get lots of packet loss, I get dropped frequently in World
of warcraft (to the point where I can't even play the game). And starting
yesterday, The speed (download) hasn't exceeded 300 kbs on 2 speed tests in
dslreports. I tested 2 times yesterday (both were at 40-62 kbs download) and
this morning at 250 kbs download speed. I signed up for a 6mb connection."

Offhand, I would say that DSL and a slower feed is fine. It seems more
important in who your data-stream supplier is and how jugged up his requests
get and how he gets his data. You can have a fast download speed, but a slow
supplier depending on how he is parsing out his requests.
Next, would be the speed of your own computer dynamics, your available
RAM, and disk access speed, contributing to your overall CPU usage. So
overall I would think you are getting your data within a fraction of a
second. To be worrying about something on the order of a few microseconds is
not worth it. More important would be the reliability and dependability of
your feed and overall computer connection.
Submitting an order electronically seems to take less than a second, and
to get a market order filled and confirmed about a second and a half.
Perhaps, the exchanges who provide the electronic order processing would
be able to give a better answer.
