hi guys

I was previously using a TOS of 136 no problem.

I changed router and around that time my TOS suddenly started showing a 8 value.

I have done lots of testing diagnositics etc. and then found out every 32 times the value resets to 0.

So here is what I mean.

0-31 TOS value works properly ...

ok it seems it isnt tcp scaling itself as it works fine at values above 65536 upto around 180k size. 180k size performs as expected and then above that kaboom a sharp drop in performance I expect its getting retransmits or something which sack handles well hence its ok with sack.

should work in windows 7, unless microsoft removed the feature between vista and windows 7.

I am seeing some odd behaviour with linux.

the settings I am looking at are the following sysctl's.

net.ipv4.tcp_rmem (controls RWIN size, 3 values, first is min used when low on memory, 2nd is default used on initial connection and 3rd is what autouning can grow the RWIN size to if required for ...

These thoughts are based on my own experience of using the tweaks and what is described on microsoft's own site for what they do.

enablefastroutelookup - little known about this but when I have it enabled web browsing has weird pauses raondomly when loading websites so I now have it turned off ...

my tips are as follows for vista.

Disable RSS unless you have both the following (a) 2 or more processor cores and (b) a network card that can handle RSS, typically a business intel pro 1000 MT card (expensive model). The intel pro 1000 PT/GT consumer model doesnt do RSS.

I cant edit some parts of my settings in usercp, most notable my profile.

It says I dont have permissions to access the page.

I changed my TOS to 136 and the net seems fine and in some cases more snappier but my router itself is defenitly treating as very low priority. Accessing my router's gui in my browser is hideosly slow taking about 10 seconds for each icon to load. So I hope no other routers on the net treat as the ...

I think your isp is changing to 0, I had a similiar situation and someone told me not to worry it is actually working then my isp admitted they were changing the TOs so I have now changed isps and is fine.

confirmed, changed isp and TOS now reports correct.

doesnt matter what I set to is always 32.

also confirmed now of a friend on the same isp, his TOS is completely untweaked and shows up as 32, he has 2 isps if he hooks up the same pc to the 2nd isp it shows as 0.

hi, I posted a while back about my TOS value always been 0 ignoring what I set in the registry, now I have 92 set in the registry and I noticed my TOS value is now 32. Am I right in thinking my isp is hard setting it and the fact its no longer 0 might suggest they using it for traffic shaping to ...

It slowed things down or seemed to and I believe my isp is forcing TOS 0 setting.

My isp is a uk adsl provider using BT ipstream wholesale adsl.

I read a SIN tech document from BT wholesale and found out they use DSCP headers to differ prioritised traffic from normal traffic using 001010, for this ...

Hi I have tried numerous times to get TOS to a non 0 value but it isnt working. So I can only assume something is modifying the TOS value outside of my computer.

I use a speedtouch 585 router and an isp who claims they dont modify packets in anyway, no proxies shaping traffic etc.

Here is my ...
