I bought new modem and would like to get max of it.
I tried this
SG Windows Vista, Windows 7 and 2008 Server Downloads
SG Vista TCP/IP Patch
and
sg_vista_tcpip_limit_patch.zip

but I don't know if it helps in win7 64

I have Comcast Cable 30Mbps and I'm using win7 64

after tweaking My DL was const at +-2Mbps
After an hour I started to see peaks 4.26Mbps
Before tweaking I got 3.5-3.99 constantly

ok, now I see peaks at even 4.7Mbps, nice...

Are there any other tweaks for such large bandwidth?

Using Fastest Firefox :

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 : 48
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 (understand ?)

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)
