For any one who has XP Pro

[Tony2005]

some of you might already know this so this is for the people who dont.

XP reserves 20% of ya connection speed for networks (i think) bt if you dont have a network it's just a waste of bandwith.

go to

then scroll down to "Increase bandwidth by tweaking QoS in Windows XP Pro"

and your sorted :cool:

Not true - that was only a rumour.
That is only true when running QOS over networks for applications like VOIP , Video stream and the 2000 Web server audio/visual streams extensions for IIS web server.

Intalling and enabling QOS service actually seems to improve my internet performance - dont know why - just is!!!

[AllGamer]

I always dissable it

when enabled it gets slower, when not installed my internet is super fast

:t

[Tony2005]

really?? i never knew that i did what that site told me and i got some extra bandwith..must be lucky:)

[AllGamer]

well it's true actually

true about being faster

but is also true about being Bull that it reserves 20%, cuz that's not happening

what is true about that is that it does a Load balancing of Packet differentiation and blah blah blah, buncha technical ****


so basically if that option is installed and enabled, it will allow those with priority to go in first VIP style

but if you kill that feature

then every networking traffic, gets the same priority

so no more VIP ****

and that's what makes things goes faster

:t

oooooh rite i get ya - cheers for the answer Allgamer:t

Hate to disagree but Ive been installing/configuring/troubleshooting QOS for a year now and it shouldnt cause problems!!! I think you may be referring to the fact that all browser outgoing internet traffic has to go through the TCI API but that should be negligible. Anyway QOS packet scheduler isnt installed by default - it has to be installed by the user so shouldnt affect most ordinary users anyway. Routers also cause problems with QOS - I have cable so its not so much of an issue.I also recently ran numerous tests on virtually all possible network settings to see if I could increase my connection speed right down to the NIC hardware parameters such as TX/RX threshold etc and QOS on or off on either a cable or dialup connection makes 0% difference in speed.

There is also a bug in the rsvp dll which can cause cpu problems. Either of these may be the issue with your machine Allgamer!!!

We use it at work - mainly because we use vlans and need to have vlan 4 (our main servers) with more priority as we are running intranet , web , email all on the same vlan for security and intranet streaming.

Interesting - Have you actually measured this increase in internet speed or is it more of a perceived increase? - what sort of traffic is it that you tested it with - audio/video streaming? http? ftp? Are you receiving QOS tagged internet traffic? QOS is more commonly used with UDP traffic as I said earlier VOIP and Realnetworks etc

I have heard that if you are running xp/2000 without the latest service pack it does cause problems because of the fact QOS had a lot of bugs early on."If the network adapter that is in use has hardware checksums enabled, the Windows 2000 Quality of Service (QoS) packet scheduler might send the wrong checksum in the packet. The QoS packet scheduler can become slow when IP packets use a QoS flow and filter by using traffic-control functions."

Be interesting to know the % increase in thruput you get but I'm sure you'll find little more than a couple of seconds either way!!!

[AllGamer]

the machines or the entire network has no problem

and yes latest in everything

and no we simply don't use it

we tried it and didn't like it

and the speed difference is Negligent

at full stream

the different was 100 kbps slower with it enable than without this is internal transfer

if you do internet trasfer the speed difference is even less

so as i said early that's why we saw it futile to use it

not to mention the trouble of having to setup all the machines and software to use it

nah... too much hassle :D, or simply lazy :p

I see - I was referring to internet usage - Yeah does have an effect on an internal network if yer not really utilizing it directly for QOS services. The original question was aimed at home users though who wont notice the difference anyway.

In internet tests I was testing using a 128k link (we're your poor relatives in the UK Im afraid - Uk peeps are just starting to get the DSL/Cable bug).
I take it your were using a 512 or a T1 where you'll be able to see the difference a bit more?

Have to agree - setting it up was a nightmare - even more so in testing to get it just right - Id never want to do it again but to see the multicasting video and conferencing at the end of it all made it worthwhile - I was impressed and its not often that Microsoft product enhancements impress me!!!
