Then select "Apply Changes" and reboot to take effect

How to get MTU ?
Just use TCP/IP Analyzer http://www.speedguide.net:8080

How to get proper RWIN ? (TCP Receive Window)

RWIN DEPENDS ON FOLLOWING FACTORS

+ Bandwidth
+ Which country we are in
+ Which country we surf frequently

Formula

RWIN = BANDWIDTH (DOWNLOAD) * MAX.LATENCY /8

MAX.LATENCY : we should only assume worst latency to the country we surf to most often and stick with it.

+ We should make RWIN an EVEN multiple of MSS

+ Satellite or Wireless should use larger RWIN values because of the high latency

AFTER ALL THOSE CALCULATIONS, HERE IS A VERY ROUGH BREAKDOWN OF THE ****YZER RECOMMENDED VALUES...

If MTU = 1500

513920 -- works for ~8 to ~30 Mbps
256960 -- 2 to 14 Mbps
128480 -- 1 to 5 Mbps
64240 -- works well up to ~2 Mbps.

If MTU = 1492

511104 -- works for ~8 to ~30 Mbps
255552 -- 2 to 14 Mbps
127776 -- 1 to 5 Mbps
63888 -- works well up to ~2 Mbps.

If MTU < 1472

+ Log into your modem/router and set MTU according to your connection type.
+ LEAVE RWIN BLANK and Uncheck Window Scaling
+ Use WinSockFix
+ Update your modem's firmware to get higher MTU
+ Uninstall tweak programs like cfos Speed


If TCPOptimizer can not adjust your RWIN , try enter the value for DefaultReceiveWindow in Cablenut

Windows Scaling
Check Windows Scaling when RWIN > 65535

Constant Values:
Custom settings - check
Modify All Network Adapters - check
TTL - 64
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
Timestamps - uncheck
MaxConnectionsPerServer - 10
MaxConnectionsPer1_0Server - 10
Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0
ToS: DisableUserTOSSetting - 0
ToS: DefaultTOSValue - 80
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768

LocalPriority - 5
Host Priority - 6
DNSPriority - 7
NetbtPriority - 8

Chech your modem/router signals

Why ? : figure out : lag, slow , disconnect issues...

Trace complete.

How to read tracert :

Hop 1 : shows signals between modem & PC, It should be 1ms 1ms 1ms ! Higher or occur * or Request timed out=> not good !

Hop 2: shows signals between modem & ISP It should range from 10 to 40 ms ! Higher or occur * or Request timed out => not good !

From Hop 3 to trace complete : ISP Network Signals, * or Request timed out => Not Good !

How to fix Hop 1 & 2 issue :

+Turn off modem/router for 10 minutes, relocate them to some place that are a few feet away from ALL other electrical devices, including apart from each other.Also, make sure you do not coil up any excess length of signal or power cables.

Then do a tracert again ! Hope this helps !

If not :

Do a full scan for malware/spyware with :

Ad-aware
Spybot Search & Destroy
Superantispyware

+ Disable unnecessary items :

Start > Run > type "msconfig" > StartUp tab > Uncheck unnecessary items

+ Using OpenDNS :

Start > Control Panel > Network Connection > Choose your Network > Properties > Internet Protocol (TCP/IP) > Properties > Use the following DNS server addresses => 208 67 222 222, 208 67 220 220.

Firefox Tweaks :

Firefox SSE2 Optimized tete009 aka Namoroka (considered fastest Firefox):
http://www1.plala.or.jp/tete009/en-US/software.html

Why ?

Browser Bench Mark by Future Mark : http://service.futuremark.com/peacekeeper/

For Specs : 1.5 mbps line, E5200, 2GB RAM, G31 Intel Graphics

With Normal Firefox:


With Namoroka tete009 :



Running Firefox on RAMDISK :

This procedure helps Firefox faster boot and faster access Awesome Bar (address bar) than the hard drive many times.

First you download the program Vsuite RamDisk (Public Edition) Free http://www.romexsoftware.com/download/ After downloading, click on the icon VSuite Ramdisk (Public Edition) on the Desktop to run the program. The main interface contains the following options:

Disk Size: RAM disk size
Drive Letter: Choose a name for the RAM drive (eg R)
File System: NTFS
Volume Labe: Naming the RAM drive (eg RamDisk)
Enable NTFS Compression: Enabling NTFS file compression
Enable Image File: check "Save at Computer Shutdown", Save format: Direct Mirror. Because files loaded into RAM they will be automatically deleted after booting Windows! With this function you can keep files to run later. This file will be saved as VDF format, only to be placed on the Windows drive (usually drive C)

However, this feature also slows down the boot time of Windows, due to loading VDF file on startup. Image File will be using Disk storage size, the larger the Windows boot time slower, so keep at 100 Mb (SATA speed that can manage)

After setup is completed, select Add. Vsuite will simulate a RAM drive R: \ on your computer. You now have a virtual hard drive with fast access speed. Done, go to Windows Explorer > Copy the files in the Firefox installation directory (usually Program Files \ Mozilla) to Firefox RAM drive. Now, you have a Firefox RAM.

Also, if you want to intergrate addons, bookmarks ... try the following procedure:

In R: \ Mozilla Firefox folder > create a folder named FFProfile , then copy whole folder C: \ Documents and Settings \ [Username]\ Application Data \ Mozilla \ Firefox \ Profiles \ ******** . default \ folder FFProfile. (8 stars stands for 8 random characters ) to FFProfile

Create Firefoxram.bat

start firefox.exe -profile FFProfile -no-remote

Then save as name Firefoxram.bat (Save as type is All Files) in directory R: \ Mozilla Firefox.

Run Firefoxram.bat to activate Firefox RAM!

Conclusion:

Benefits:

+ Fix the slow startup time of Firefox, especially after booting Windows, very useful when you install multiple addons (extensions), large bookmarks, large cache size - those components affecting performance of Firefox.

Disadvantage: Make Windows boot a bit slower due to image file (VDF)

+ How VDF file affects Windows boot time (tested on the Seagate HDD 7200 RPM 8 MB Cache )

RamDisk capacity:

512 MB => Long boot time
200 MB => Acceptable boot time
120 MB => Almost Normal boot time

It may vary depending on the type of your Hardisk !

Note: If you want to remove the Vsuite RamDisk, disable your RAMDISK first !

Firefox Popular Tweaks :

FireFox > type about:config in Awesomebar (Addressbar) > type connection in Filter then set :

network.http.max-connections : 32
network.http.max-connections-per-server: 16
network.http.max-persistent-connections-per-proxy:16
network.http.max-persistent-connections-per-server:8

FireFox > type about:config in Awesomebar (Addressbar) > Right click on blank space > New > Integer > type nglayout.initialpaint.delay > 0

FireFox > about:config > Filter: pipelining > network.http.pipelining > true

FireFox > about:config > New Integer > network.http.pipelining.maxrequests > 8

Using Addon for Speed

+ Ablock Plus
+ Element Hiding Helper (kill text ads just press Ctrl+Shift + K )

+ ImglikeOpera & Noscript (you must be a Firefox Geek)

TCP Window size depends on bandwidth and max. latency and different countries or different continents will have different rules of thumb.

Default ToS value can be different. Suggested values that conform to both ToS and Diffserv standards are 80, 104 and 136 - http://www.speedguide.net/tcpoptimizer.php#advanced_qos

Some ISPs may not accept any value set to it other then zero.

Could You tell more , Trogers ?

Could You tell more , Trogers ?

The differences are due to differing max. latency - the time for a full sized packet to make the round trip. Thus it depends on where you are and which country you surf to most often.

If we use the US as the most surfed to place, then latency for users in East and South East Asia will be 450-550ms depending on time of day.

A user in the US will only face latency of 90-130ms. Thus TCP Window Size will be different for the same bandwidth.

How about latency for users in West ?

How to deal with the DISTANCE PROPBLEM ?

Sometimes , the TCP Window is left BLANK , Could you explain?

I am using WinXP Pro and the Group Policy (gpedit.msc) has worked properly.

You can try "Regedit"

I believe gpedit.msc is only available in Windows Server 2003, Windows 2000, or Windows XP Professional and not XP Home.

[jasonb31]

Regedit pulls up all kinds of things. I dont have a clue what to do after pulling that up, Even if something can be done there.

You cannot set QoS to zero with regedit.

[karak]

Im new here so hello to all. What i used was FRESH UI, windows xp home does not allow for this function, so FRESH UI came in very handy.

[Rollingstone]

You cannot set QoS to zero with regedit.

I believe it is QoS: NonBestEffortLimit - 0 in TCP Optimizer !

[JACOMO]

PLEASE I NEED HELP!!!!!!!!!!!!!

CAN I USE 65535 IN LAN REQUEST BUFFER SIZE, USING TCP OPTIMIZER?

THE PROGRAM SUGGEST 16384 IN OPTIMAL SETTINGS AND SOMEBODY TELLS 35540.

MY EMAIL IS jai1732@gmail.com.


regards.

If the optimizer makes my internet worse. How do I restore back my original settings?

[mccoffee]

In the optimizer click on file then should be a reset to default or default settings.
