[Cable] Tweak Me Baby

Actually you are getting above the 16mb download cap and over the up cap. You can try this,but I don't think that you see much (if any) improvement.

Is the increase OVER the existing 16/2? Or is 16/2 the new cap?

Download DrTcp

Set Tcp Receive Window to 128560

Set Selective Acks, Path MTU Discovery, Black Hole Detection to Default.

Leave Max Duplicate Acks and TTL Blank

Using the drop-down menu in The Doctor set your NIC’s (Ethernet adapter’s) MTU to 1500.

Save/Exit DrTcp

Reboot

Rerun the Tweak Test

Run Two Speed Tests from the two DIFFERENT cities nearest to you that are listed here: Speakeasy POPs

Also, test here »ftp://ftp1.optonline.net/test512

Note your transfer rate after about 30 seconds. Then cancel the download.

Post the URL for the New Tweak Test. For the TWO Speakeasy Tests, Copy and Paste the speed results from those tests and note the speed from the FTP download test.

Yes the increase is over the existing 16/2 tier. Although I'm not sure if I have Blast or not? Hell, I don't even really know if I'm on 16/2? I'm just going by what I've read here at DSLR and speed test comparisons. Comcast is very secretive about such things so it's hard for the customer to know what he/she is getting?

I have Performance, whatever that means?

EDIT: If I'm on a 16/2 tier then a 25% increase should be 20/2.5

So if I was on a 16/2 tier then it looks as though I have the 25% increase download speed and 50% upload speed.

Thanks for help. The tweak test looks better now.

You can try a RWIN of 144540 and see if you can squeeze anymore out of that line.

Not much there. Put the RWIN back to 128560.

Do you have a router? If so, make sure the MTU is set to 1500 or Auto.

There is a mismatch on your your MTU.

A bit slower with RWIN back to 128560.

My sincere thanks to you. I can see how your tireless effort is taken for granted. Someday I hope to return the favor?
