QoS Packet Handling

[Charlie''s Word VBA questions]

I have Windows XP, Home Edition, on a Dell 4700. There is no connection to
any other computer. I am on a 756k DSL. I have sent an email attachment of
about 6.5 mb that takes nearly 30 minutes. When I look at networking under
Task Manager, the Network Utilization averages about 0.03%.

When I disable QoS Packet Handler in Network Connections, the Network
Utilization goes up to about 0.50% (over 10 times faster) and the file is
sent in under four minutes. However, the problem returns, seemingly on a
random basis.

Then, I also disabled QoS RSVP in services.msc which seemed to solve the
problem. But, again, the problem returns on a random basis.

In trying to figure out what happens when it is running so slow, I have
turned on the QoS Packet Handler and immediately turned it off. That made it
run at the higher speed. But, then the problem returns again.

What starts QoS? Is there a way to permanently disable it without
uninstalling it? To avoid uninstalling QoS (since it might be a real problem
if I need to reinstall it), what might happen if I simply rename the
executable RSVP.exe? Or is there another solution?

This one is driving me nuts. I sincerely appreciate any guidance you can
offer.

QoS is Quality of Service scheduler and requires a router with the
'server' feature on it. It is used the "shape" the Internet traffic
going in/out but placing a priority to different Internet protocol.
Usually usefully is setting Internet priority so that high volume
traffic (VoIP) can use your Internet access before your other Internet
accesses.

If you do not have a router or your router does not use QoS, you can
uncheck it.

Thank you. However, I understand what QoS is. However, that doesn't deal
with the question of how to turn it off permanently (but not uninstalling
it). Note that I am not networked to any other computer or server. I use
email and the web only. Simply unchecking QoS does not turn it off and
disabling it in services.msc does not prevent it from somehow restarting.

AFAIK, rsvp is no longer in use for WinXP and Vista.
Maybe you have registry settings (group policy?) that
cause throttling by the QoS scheduler (a.k.a. psched).
The qos scheduler is optional, you can disable it
unless you know you need it for something specific (games, voip...)

Hi
Hi
Did you optimized the TCP/IP for DSL connection?

I downloaded and ran the DrTCP021 program. TCP Receive Window and Max Acks
were blank while all other options were set as "Default". However, I also
noted that the "Connect using:" property for Local Area Connection in the
Control Panel is "Intel(R) PRO/100 VE Network Connection". But the DrTCP021
Adapter Settings indicate "Westell USB Network Interface" is entered in the
window. This is the modem supplied by the ISP service and is cabled to the
computer by Ethernet, not USB. (I don't know if that is because it is the
first of the options in the drop down list or if it is really being used --
the Intel PRO/100 is the last option in the drop-down.)

Does the above indicate any problems?

Please know that I am a REAL junior (I know next to nothing) about
networking or communications. So, I really do not understand very much of
what I am seeing. I only know that I have seen a "line speed" of 0.03% and a
ten-fold increase to 0.50% when QoS is off, except that it seems that
something randomly turns it back on.
