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

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


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 ANALYZER 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

Host Resolution Priority

LocalPriority - 1
Host Priority - 1

or (more prefer)

LocalPriority - 5

DNSPriority - 7

REMEMBER

+ Relocate your router and modem in proper place :
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.

+ Scan for Spyware/malware:

We recommend



+ Disable unnecessary items :






+ Disable unnecessary services :



+ Using OpenDNS :


+ Fake IP and Save Bandwidth with Toonel :
Toonel is an experiment in a technique for conserving network bandwidth. If you are paying a fee based on the amount of data you transfer (e.g. 3G/GPRS/DSL/CDMA) and have monthly download limit, or if you have narrowband connection (e.g. dialup modem) then you are most likely to appreciate the service toonel.net offers (http://toonel.net).

Note : It requires Java Environment (http://java.com/en/download/index.jsp)

Set the following proxy for Browser: 127.0.0.1 Port 8080

Speed Hacks

1. Pipelining: By default pipelining is disabled in Firefox. Usually when we visit a site the browser will make only one request to the server but while Pipelining is enabled it makes more than one request.It works like a download accelerator. You will notice a great change in speed while accessing sites in slow server.

In the filter bar type network.http.pipelining. You will be shown the result that matches your search. The first one will be network.http.pipelining itself with a boolean variable. Check the value, if its false double click and make it true

Next you will find an network.http.pipelining.maxrequests just below the previous line. Its an integer value with 4 as default. Change the value to 10, 20 or even 30. Test different values and see which one is optimum for your connection

2. Rendering Delay: Now create a new integer by right clicking anywhere and selecting Integer from New. Give the name as nglayout.initialpaint.delay and the integer value as 0. This specifies the amount of time the browser waits before rendering the page with information it got. You will find the page loading part by part but this is a useful hack as texts will be displayed first.
NOTE: If you get a lot of “Page not found” error after applying this, then try to increase the value from 0 to say 2 or 3.

Summary:

* Set network.http.pipelining to true
* Set network.http.proxy.pipelining to true
* Set network.http.pipelining.maxrequests to 20 or whatever value you like
* Create a new integer called nglayout.initialpaint.delay and give its value as 0

Optimize

Ever noticed of instances when Firefox’s CPU usage shoots up to 90% and the Memory usage shoots up to anywhere between 200 MB and 700 MB(this happens if you dare to open 200+ tabs like this gal tried )? Read on for some tips to improve the situation.

1. Excellent tips from Zolved (go to the site for detailed instructions)

Check your Extensions and Themes.
Check the Plug-ins.
Clear Download History.
Restart Firefox Periodically.
Assign Memory Cache on Firefox.
Release Memory when Firefox is minimized

2. Disable prefetch: Firefox has a nasty habit (sometimes this is useful) when you search in Google. It automatically loads the sites you are likely to visit like the first result. Disabling these can be a good idea for people with low-speed internet connection or low RAM. You can also disable this if you are bandwidth miser :P. To do this type in network.prefetch-next in the filter box and double click the value to turn it to false.

Summary

* Disable unwanted Extensions
* Disable unwanted Plug-ins.
* Clear Download History.
* Restart Firefox Periodically and don’t hibernate/sleep your computer while Firefox is running
* Set browser.cache.memory.enable to true, create a new integer named browser.cache.memory.capacity and give its value equal to 16 times your RAM capacity in MB (16 X your RAM size which is usually 256 or 512).
* Create a new boolean value named config.trim_on_minimize and set it to true
* Disable prefetch by toggling network.prefetch-next to false
