creep · Post by **creep** » Sat Sep 22, 2001 2:07 pm

sorry, but i couldnt find the post where lobo goes into specifics as to tweak XP aside from helping other ppl with their xp probs.

so.... with that being said, are there any speed tweaks i can use or settings i can change to tweak my cable connection using xp?

Tweaks for Windows XP

1.) Turn off System restore and auto updates.
2.) Use SG's System ini tweak set at 7168, type sysedit in run box, Close out of all boxes except System Ini, put it in 386th Enh, thats where it goes , see if it helps you are not, if you don't have alot of RAM it might not.
3.) Go to control panel, system, advanced tab at top,performance, settings, click on best performance,then advanced tab at top, background services, then programs
4.) 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
5.) Use Win 2000- patches for XP
6.) Yes Cablenuts adjuster works with XP
7.) This is the neatest, do it and come back to forum,
Click Start, click Control Panel, and then click Appearance and Themes.
Click the Display icon, click the Appearance tab, and then click Effects.
Click the Use the following method to smooth edges of screen fonts check box to select it, and select ClearType from the list.
Click OK, and then click OK again.
8.) This was for WIN 2000 but it works in XP too, I use it:
Here's a great tip to speed up your browsing of Windows 2000 machines. Its actually a fix to a bug that by default of a normal Windows 2000 setup that scans shared files for Scheduled Tasks. And its turns out that you can experience a delay as long as 30 seconds when you try to view shared files across a network from as Windows 2000 is using the extra time to search the remote computer. Note that though the fix is originally intended for only those affected, Windows 2000 users will experience that actual browsing speed of both the Internet & Windows Explorers improving significantly after applying it since it doesnt search for the Scheduled Tasks anymore. Here's how :

9.) This make broswing alot faster, but if you use scheduled tasks, don't do this,
Open up the Registry and go to :

HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace

Under that branch, select the key :

{D6277990-4C6A-11CF-8D87-00AA0060F5BF}

and delete it.

10.) Auto Logon XP
real easy and straight forward.

1. click on "Start" - then click on "Run" - type "control userpasswords2"

2. click OK

3. On the Users tab, clear the "Users must enter a user name and password to
use this computer" check box.

4. A dialog will appear that asks you what user name and password should be used to logon automatically.

Your all set.

11.) One of the most full featured Windows XP configuration tools available is hidden right there in your system, but most people don't even know it exists. It's called the Local Group Policy Editor, or gpedit for short. To invoke this editor, select Start and then Run, then type the following:
gpedit.msc

12.) You can easily create a bootable floppy disk by following these steps:

Place a blank disk in the floppy disk drive.
Click Start, and then click My Computer. Or My Computer Icon on desktop
Right–click the floppy disk drive, and then click Format on the shortcut menu.
Click Create an MS–DOS startup disk, and then click Start.
Now you’re on your way to a bootable startup disk.

13.) NIC Buffer tweaks:

InitialLargerBufferCount- 50
InitialMediumBufferCount- 100
InitalSmallBufferCount-150
LargerBufferSize-40960 M E D-LARGE RWIN
MediumBufferSize-7215
PriorityBoost-2
SmallBufferCount- 1024

InitialLargerBufferCount- 100
InitialMediumBufferCount- 500
InitalSmallBufferCount-800
LargerBufferSize-40960 SMALL-RWIN
MediumBufferSize-7215
PriorityBoost-2
SmallBufferCount- 1024

See RWIN, should be 256960, you have proxy enabled, direction in help thread below to dis able, don't forget to REBOOT

creep · Post by **creep** » Sat Sep 22, 2001 5:49 pm

Doh! i totally forgot about the proxy.
I turned it off in internet explorer and ran the test again.

So, then if i use the proxy for the web-browser, XP uses it for everything else too? because as soon as i disabled it, my ftp sends were back up to 40k.

Lobo · Post by **Lobo** » Sat Sep 22, 2001 5:59 pm

No, there is only one way to do it, above

creep · Post by **creep** » Sat Sep 22, 2001 6:01 pm

i just edited my last post.. check it out if you havent seen it yet

Lobo · Post by **Lobo** » Sat Sep 22, 2001 6:05 pm

Bring up Cablenuts adjuster inside Cablenut on desktop the numbers below go in 3 places in W2k and XP, they are: DefaultReceiveWindow, TcpWindowSize, GlobalMaxTcpWindowSize, take out number that is in there and put in one of these, 1 at a time, try: 417560, 420480, 438000, 449680

Proxies are no good, RWIN will always be 49152 with it on

You do not have to show me but check analyzer here at SG to make sure RWIN is in, you will see number right after (RWIN) on analyzer

At bottom click save to registry, and REBOOT each time you change value in adjuster or it will not work. Click on tools at top of IE, internet options, delete files and offline files (This is safe, temp files) and click on clear history after EVERY test . Quick speed test here
Speedtest may open another browser, so check taskbar and close other, no other programs should be running, No AIM, ICQ, Virus scanner, Firewall, nothing
Once you find fast number for you, you want to save it, on file at top of adjuster click on that, save custom settings, put RWIN size in as name and click on save, now if you ever want these settins back, click on file, open custom settings file, and click on RWIN number, then click on save to registry at bottom, and REBOOT, your done. How to do real dowwnload test on help thread below in signature.

creep · Post by **creep** » Sat Sep 22, 2001 6:50 pm

ok did all that... here's my test results

Test running..Downloaded 60900bytes in 701ms
Downloaded 696000bytes in 3285ms
First guess is 1694kbps
fairly fast line - now test 2mb
Downloaded 1679100bytes in 7862ms
Upload test not enabled

** Speed 1708(down)/na **
(At least 34 times faster than a 56k modem)
Finish.

that a good result?

Looks good, will be faster late at night or early in morning, how to save your settings in adjuster in help thread

creep · Post by **creep** » Sat Sep 22, 2001 9:08 pm

YUp, i saved my settings in cablenut adjuster.. not to worry

thanks for your help dude

creep · Post by **creep** » Sat Sep 22, 2001 9:35 pm

ok, i don't know if you'll be able to help but here goes...

before i installed XP i had approx. 2.5gb on my c:\ and after i have just a little less than 300mb. Now, XP couldn't have taken up all that space. could it?

any ideas?

creep · Post by **creep** » Sat Sep 22, 2001 9:53 pm

I just added up all the contents of all the folders in C:\ and got 2gigs... so there should be another 2gigs free... but it shows up as 463mb free..

this is really bothering me

can you help?

Lobo · Post by **Lobo** » Sat Sep 22, 2001 10:43 pm

No XP is only 500 and something mb's, bring up C drive in explorer or my computer, RIGHT click on a blank place, select properties, then tools, Error checking select now, check both boxes in there and it will start when you reboot

creep · Post by **creep** » Sat Sep 22, 2001 11:25 pm

so just try a full scan disk action then huh? alright, ill give it a shot

Lobo · Post by **Lobo** » Sat Sep 22, 2001 11:50 pm

Thats how you recover lost clusters, probably speed you up too,
Should do this every week not the long one but the first box

creep · Post by **creep** » Sun Sep 23, 2001 12:08 am

So should i have both boxes clicked or just one? cuz you said have both then said one..

Lobo · Post by **Lobo** » Sun Sep 23, 2001 12:11 am

I would check both the first time then the 1st one every week after that until you think you may need to check both again, 10-fer

drdoug99 · Post by **drdoug99** » Sun Sep 23, 2001 12:22 am

check your system restore files. I have my turned off, so it doesnt take up space. I have a 4gig partition for XP, and 1.5 of that would be taken up by system restore. If so, then thats your problem.

creep · Post by **creep** » Sun Sep 23, 2001 11:52 am

Yeah, i turned off system restore also, but can you tell my which folder they are kept in?

creep · Post by **creep** » Sun Sep 23, 2001 9:20 pm

Where are the backup for the system restore option kept?

on c:\ i suppose, but where?

creep · Post by **creep** » Sun Sep 23, 2001 9:26 pm

I did that scandisk with both boxes checked and it said that 1gb was in hidden files.

SO that's where my missing space is... BUT i set it so that windows shows ALL files even hidden and system files and STILL can't find it.

please help

creep · Post by **creep** » Sun Sep 23, 2001 9:37 pm

ok, i found it.
i had to really look for it. in the folders option, there was a check box that said, 'show windows protected files' so i checked that.

it was located in C:\undo

i got back about 400mb

anyone know any thing else i can delete to free up space?

jsjaedon · Post by **jsjaedon** » Mon Sep 24, 2001 3:22 pm

Can someone show me manually where exactly in the registry of WinXP i can tweak the RWIN values?!!? please!

thanks

Lobo · Post by **Lobo** » Mon Sep 24, 2001 3:25 pm

Download to desktop DRTCP019.exe, you may change alot of settings with this, first select your adapter, after changing anything play with it until apply button lites up, then click on it. Then REBOOT for it to work.

http://www.dslreports.com/front/drtcp.html

Change RWIN with this tool where it says Tcp Rvc Window, then reboot

jsjaedon · Post by **jsjaedon** » Mon Sep 24, 2001 6:32 pm

it doesn't work!

I still get 1460 as my defaultRcvWindow.....and btw I am running WindowsXP professional.

Some people are saying it's practically the same as win2k. I just want to see exactly where those programs actually edit the registry, so that I can do it manually and make sure it's done right.

Thanks

Lobo · Post by **Lobo** » Mon Sep 24, 2001 6:36 pm

What company did you download xp from, because if it is not the right one, you may be out of luck, and no Microsoft is not the answer, they sold it, but did not ship it

jsjaedon · Post by **jsjaedon** » Mon Sep 24, 2001 6:59 pm

Devilsown
My version of XP is from DevilsOwn.

Do you think I could be capped by my school's ethernet? is that possible? since im connected to their ethernet, i can't get a rcvwindow greater than 1460?

funky · Post by **funky** » Mon Sep 24, 2001 7:25 pm

Get Cablenut @ http://www.broadbandnuts.com . Works well with XP, change the DefaultRCVWindow, sendwindow, TCPWindowsize, and GlobalmaxTCPwindowsize with the Rwin you want to use.

jsjaedon · Post by **jsjaedon** » Mon Sep 24, 2001 7:40 pm

damn, none of the options mentioned works. I can't get speedguide tcp/ip tester to read anything above 1460 for my defaultrcvwindow!!!
