TCP/IP Connectivity in XP

[Nevada]

i'm looking for information on increasing TCP/IP connectivity performance in Microsoft XP.

Download DrTCP: http://www.dslreports.com/front/DRTCP021.exe

Run the program, it will show the current settings of TCP/IP parameters. Write them down.

You can change any variable that you want, click Apply, and reboot the computer, if no good; you can always change to your original values.

Start with:

MaxMTU - for DSL =1492, Cable=1500, ISDN -1322, DialUp=576

Tcp Receive - 256960 (This is the variable to play with).

Window Scaling - Yes

Time Stamping - No

Selective Acks - Yes

Path MTU Discovery - Yes.

Black Hole - NO

Max Duplicate - 2

TTL - 64

Notice it said above Start with

These settings are not written in "stone" there is variability depending on the computer other setting. So try few setting and measure your Download for each setting.

In addition, in case a person has a Router the Router's MTU if set differently can affect the general MTU.

Of course it helps to actually KNOW what what those settings "mean" than just arbitrarily changing values.

I don't know how you guys are -- but I have this thing that I MUST KNOW info about stuff before I change it.

Even if you just know the basic definition of each setting that's a good start.

CISCO.com and webopedia.com can help you out if you are a novice (of course you could be more knowledgeable than me in networking and I'm an engineer, but hey we are strangers I don't know you -- so please don't take offense to what I typed here. For all I know you are freaking Bob Metcalfe (if I spelled his name right..lol))

later.

I totally agree with you. I am working for a company and they just give me a script which say if they have this error run this and for that error run that.

I want to know what I am running before I run it eventhough it fixes the problem. But the person told me that they have no idea and that it works.
