i am running on a 2mbps internet connection, i was wondering how i can speed it up a little more...

here is my result using TCP analyzer

Why u recommend 0? I use to set this to 254 and i can achieve half of megabit more in my connection. im asking because i dont know what is going on with the isps around there

http://www.speedguide.net/tcpoptimizer.php#advanced_qos

ToS: DefaultTOSValue - 0 => class 0, default (routine)

ToS: DefaultTOSValue - 254 => ?

254 = 111 111 10

111 => Network Control
1 => Low Delay
1 => High Throughput
1 => High Reliability
1 => Low Cost
0 => MBZ checking bit (Must Be Zero)

hmm, "ToS = 254" so weird setting for me.
recommended TOS Value => 0(default), 80, 136 & 184 => depending by DiffServ Field

maybe i need an rfc refresher but as said above sometimes another server sets that value.

yap, but he was said

normally last 2 digit always set "00", for decimal 254 last 2 binary digit "10".
that setting abnormal for me

one more thing

give me ur speedtest result for
ToS: DefaultTOSValue - 254 &
ToS: DefaultTOSValue - 0

I'm not sure how the tos seting would give such a speed burst unless it's matched with your setting matched the isp server even then i don't think it would have that much impact on speed.

I admit i do need to re read up on it i could be wrong.

11111110=254, i know that this is overall network control, and the last digit must be zero, i'll check it out once again when ill find an xp machine and time. remember that my package is 24/1mbit (22/1 sync) over dsl and i mean that, i can achieve 19,7~8 and without tos value or even less about 19,2 or something like that.

So guys,
this is my xp machine and as u can see i have set it to 254. this is my best setting. No problem with page loading or other. im not equivalent, but does not matter, works fine

edited: After several speedtests, i dont see any differences in dl speeds (weird, before 2 years i swear in, that i have seen differences) but the general internet response times, are much better with tos 254.

Could be that your ISP has adjusted network control to be equal to 0...lol

Hi trogers,

im not sure if that can exists, cause if tos is been overwitten by your isp, it will be shown in any analyzers

what is ur settings for :
ToS: DisableUserTOSSetting
ToS: DefaultTOSValue

u already know the answer. u can see it in the analyzer but,(irrelevant) why those 2 are shown in low mode? they must be shown as high

Throughput: 1 (low throughput)
Reliability: 1 (low reliability)

no i dont

in my case:
i set TCP Optimizer Settings
ToS: DisableUserTOSSetting = 0
ToS: DefaultTOSValue = 0

my TCP Analyzer Result
IP ToS: 10001000 (136)
Precedence: 100 (flash override)
Delay: 0 (normal delay)
Throughput: 1 (low throughput)
Reliability: 0 (normal reliability)
Cost: 0 (normal cost)
Check bit: 0 (correct)
DiffServ: AF41 100010 (34) - Assured Forwarding class 4, low drop precedence (RFC 2597).

see, i cannot read ToS Settings from TCP Analyzer result

so, what is ur settings @ TCPO?
ur case very interesting for me

ok.....

ToS: DisableUserTOSSetting = 0
ToS: DefaultTOSValue =254

in your case the tos is written by your isp, in my case nope

100 010 00 wrote:ok.....

yap in my case ToS was overwritten by ISP.
n ur right they must be shown as High
http://tools.ietf.org/html/rfc791#page-12

now i know the problem?
TCP Analyzer issue for our both case

my TCP Analyzer Result
IP ToS: 10001000 (136)
Precedence: 100 (flash override)
Delay: 0 (normal delay)
Throughput: 1 (low throughput) => high throughput
Reliability: 0 (normal reliability)
Cost: 0 (normal cost)
Check bit: 0 (correct)
DiffServ: AF41 100010 (34) - Assured Forwarding class 4, low drop precedence (RFC 2597).

ur TCP Analyzer Result
IP ToS: 11111110 (254)
Precedence: 111 (Network Control)
Delay: 1 (low delay)
Throughput: 1 (low throughput) => high throughput
Reliability: 1 (low reliability) => high reliability
Cost: 1 (low cost)
Check bit: 0 (correct)
DiffServ: No valid DiffServ equivalent (111111)

i will fw to philip, hope he can help

im sure he can help, these are just 2 variables.

Thanks for catching that. You're right, seems the values are correct, just that the descriptions were wrong on those two throughput/reliability ToS settings.

It's been corrected.

Oh, and here are the ToS values from the RFCs, they're listed in the tables: http://www.speedguide.net/tcpoptimizer.php#advanced_qos

The only problem with ToS of 254 is that it does not have a DiffServ equivalent, which is a bit newer QoS variant. In a DiffServ environment, it may be better to set it differently, as per the DiffServ table in the above link.

re-check

IP ToS: 10001000 (136)
Precedence: 100 (flash override)
Delay: 0 (normal delay)
Throughput: 1 (high throughput)
Reliability: 0 (normal reliability)

Check bit: 0 (correct)
DiffServ: AF41 100010 (34) - Assured Forwarding class 4, low drop precedence (RFC 2597).

correct, thanks

so what am i going to do now?

here is my results now
