i just got win2k pro installed..

hehe...pretty confusing when installing first time.. but i know how.. hehe..

but are these ok?

TCP options string = 020405b40103030201010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 50 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

you may try one of the other suggested RTWIN values:

Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

Have a good one-

i used the followoing patches:

sguide_tweak_2k.zip
SpeedGuide_2k Web Patch
Speed Patch

and i got windows 2000 Pro.... what other patches do i need? i also got cablenut 4.02..
how would i make the chanhes? should i used the "cable_fast_2k.ccs" and make changes and save to registry?

Thanx

Lobo · Post by **Lobo** » Mon May 14, 2001 7:57 am

Calenut 4.02, I hope you got 4.0 as 4.2 updates 4.0 and I hope you got them before Speedguides as Cablenuts takes you back to default, I f you did not get 4.0, go to help page in sig below for directions, there are 3 place in W2k were we change RWIN

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 3:24 pm

3 places Lobo? I know of GlobalMaxTcpWindowSize and TcpWindowSize...what's the third?

Lobo · Post by **Lobo** » Mon May 14, 2001 3:33 pm

Default Recieve Window, this is from main page under Win 2000:
The value of TCP Window in the Windows 2000 Registry is DWORD, representing number of bytes, with range from 0 to 2^30. The recommended values (in red) optimize TCP for any high speed Internet connection and work best in most cases, however if you'd like to use a custom value follow these guidelines:

For best results, the TCPWindow should be a multiple of MSS (Maximum Segment Size). MSS is generally MTU - 40, where MTU (Maximum Transmission Unit) is the largest packet size that can be transmitted. MTU is usually 1500 (1492 for PPPoE connections). To determine the MTU value of your ISP, check out the Advanced Registry Editing section of our site.

There are three places in the Windows 2000 Registry where you can add the TCP Window parameter.

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 3:42 pm

what are they?

Lobo · Post by **Lobo** » Mon May 14, 2001 3:44 pm

1- Default Recieve Window and the 2 you listed above

Lobo · Post by **Lobo** » Mon May 14, 2001 3:50 pm

You won't see it on Cablenuts if your on 9x, W2k is alot different

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 3:50 pm

oooh...I was meaning simply for Win2k...sorry

TcpWindowSize and GlobalMaxTcpWindow size are the only two for Win2k and Default Recieve Window is for 9x right?

EvilAjax · Post by **EvilAjax** » Mon May 14, 2001 3:51 pm

Hey Lobo, I haven't gone on XP for like a week now.. How's it goin for ya? Still slow or have you finally figured it out? If so... do share

Lobo · Post by **Lobo** » Mon May 14, 2001 3:54 pm

No Win2k is the same as XP

1. Default Recieve Window
2. GlobalmaxTcpWindowSize
3. Tcp Window Size

This is not same adjuster as 9x

Lobo · Post by **Lobo** » Mon May 14, 2001 3:58 pm

Hey Evil, figured it out, I wish, it's faster than 9x but boot up is still slow, I guess thats because it's beta, I'm afraid to mess with it

EvilAjax · Post by **EvilAjax** » Mon May 14, 2001 4:00 pm

Faster than 9x??? Do tell me what you've done... if not here than please e-mail me.
evil2dafullest@aol.com Thanks bro!

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 4:01 pm

If Default Receive Window is a reg entry for Win2K, how come none of the patches add it? They only mention Tcpwindowsize and globalmaxtcpwindow size.

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 4:02 pm

Oh, I don't use the Cablenut Adjuster

I do it manually.

Lobo · Post by **Lobo** » Mon May 14, 2001 4:03 pm

Well im on cable Evil and your on PPPoE so it's different I guess

Lobo · Post by **Lobo** » Mon May 14, 2001 4:06 pm

Evil it's probably all those AOOL adapters

Lobo · Post by **Lobo** » Mon May 14, 2001 4:09 pm

Juggernaut, Patches enter default Recieve window, I think but I know it's 3 places

[ 05-14-2001: Message edited by: Lobo ]

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 4:11 pm

this is what Speedguide's enters:

"SackOpts"=dword:00000001
"TcpWindowSize"=dword:0003ebc0
"Tcp1323Opts"=dword:00000001
"DefaultTTL"=dword:00000040
"EnablePMTUBHDetect"=dword:00000000
"EnablePMTUDiscovery"=dword:00000001
"GlobalMaxTcpWindowSize"=dword:0003ebc0

Default Receive Window is added on 9x

EvilAjax · Post by **EvilAjax** » Mon May 14, 2001 4:17 pm

Nah Lobo, I meant system tweaks.. hehehe.. Internet isn't such a factor to me on XP... as long as XP runs fast, Im sure my internet Xperience will also be faster. Thanks.

Lobo · Post by **Lobo** » Mon May 14, 2001 4:23 pm

You;ll have to ask Phillip, Brent or someone, it;s 3 places though

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 4:30 pm

damn...I've only heard of two...it's only in Two on Cablenut's program as well.

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 4:32 pm

Well that gives me something to look into now...thanx a lot Lobo

I wonder where the next one will be, cuz the TCP Analyzer reads my RWin fine

Lobo · Post by **Lobo** » Mon May 14, 2001 4:53 pm

I;ve got Cablenuts adjuster and all 3 of the above are listed in Win 2000, not in 9x

Lobo · Post by **Lobo** » Mon May 14, 2001 5:00 pm

Evil this helps bootup time alot:
Disable IDE Port Scanning on empty ports and save bootup time.
Go to System Properties by right-clicking on My Computer or via the Control Panel.
Select the Hardware tab.
Look at the Device Manager section and click on the Device Manager button.
This brings up the Device Manager screen.
Open up the IDE ATA/ATAPI controllers device branch. Then you will see a list of all the IDE controllers

and channels in your system.
Now, select any one of the IDE channels, right click and choose Properties. Or just double click on the

IDE channel.
Now, select the Advanced Settings tab to get the screen below. As you can see below,

the second port (Device 1) on the Primary IDE Channel does not any IDE device attached to it.

Thus, the Device Type is labeled as Auto Detection. In contrast, the first port has a device attached. That's why the Device Type is grayed out.
To disable IDE device scanning for the second port, click on Auto Detection and you will see

two choices on the list. Select None.
Click OK and reboot. Windows 2000 will now refrain from scanning that IDE port at start up and

should load a little faster.

Juggernaut, I am sitting here looking at Cablenuts Win 2000 adjuster, the very first box says DefaultRecieveWindow

Lobo · Post by **Lobo** » Mon May 14, 2001 5:16 pm

Evil you know how to do it, post a picture of Cablenuts Win 2000 adjuster

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 5:45 pm

I know it's there

but I don't think that applies to Win2K...if I'm not mistaken, the adjuster for the 9x and Win2k are the same...that's why Globalmaxtcpwindowsize shows up in the 9x version as well and u tell people to leave it Blank. I think the same applies to the Default Receive Window in the Win2k part. All the tweaks I've seen only have Tcp Window Size and Global Max Tcp Window Size.

Lobo · Post by **Lobo** » Mon May 14, 2001 5:48 pm

They are not the same, very different

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 5:49 pm

Also, with Cablenut's tweaks for Win2k, a value for Default Receive Window isn't added either. I think it's like the Globalmaxtcpwindowsize on Win9x, where you should just leave it Blank

Lobo · Post by **Lobo** » Mon May 14, 2001 5:51 pm

There are three places in the Windows 2000 Registry where you can add the TCP Window parameter.

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 5:51 pm

I know the key placements are very different, but are the interfaces different?

Lobo · Post by **Lobo** » Mon May 14, 2001 5:53 pm

The 9x adjuster looks nothing like W2k adjuster

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 5:53 pm

Ok Ok

but is it needed :P

Lobo · Post by **Lobo** » Mon May 14, 2001 5:54 pm

Speedguide says 3 times, I just follow the Guru's

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 5:58 pm

Might I ask where they say 3 times? At http://www.speedguide.net/Cable_modems/cable_reg_win2k.shtml they only mention the two...I'm just curious cuz I'm on Win2k and wondering if that needs to be in there.

Lobo · Post by **Lobo** » Mon May 14, 2001 6:02 pm

http://www.speedguide.net/Cable_modems/cable_reg_win2k.shtml
It says 3 times down there under TCP

Juggernaut · Post by **Juggernaut** » Mon May 14, 2001 6:07 pm

doh, how did I miss that?

BUT, it is not the Default Receive Window key, it's the TcpWindowSize key in a diff location that just overrides what u may in Global. If u'r Globalmaxtcpwindowsize and TcpWindowsize are the same (which they should be anyways) u don't need it.

Thanx
