MAKE YOUR MENUS LOAD FASTER

MAKE YOUR MENUS LOAD FASTER

This is one of my favorite tweaks as it makes a huge difference to how fast your machine will 'feel'. What this tweak does is remove the slight delay between clicking on a menu and XP displaying the menu.

Go to Start then Run
Type 'Regedit' then click 'Ok'
Find "HKEY_CURRENT_USER\Control Panel\Desktop\"
Select "MenuShowDelay"
Right click and select "Modify'
Reduce the number to around "100"

This is the delay time before a menu is opened. You can set it to "0" but it can make windows really hard to use as menus will open if you just look at them - well move your mouse over them anyway. I tend to go for anywhere between 50-150 depending on my mood.

Speed Up Browsing

When you connect to a web site your computer sends information back and forth. Some of this information deals with resolving the site name to an IP address, the stuff that TCP/IP really deals with, not words. This is DNS information and is used so that you will not need to ask for the site location each and every time you visit the site. Although Windows XP and Windows XP have a pretty efficient DNS cache, you can increase its overall performance by increasing its size. You can do this with the registry entries below:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters]
"CacheHashTableBucketSize"=dword:00000001
"CacheHashTableSize"=dword:00000180
"MaxCacheEntryTtlLimit"=dword:0000fa00
"MaxSOACacheEntryTtlLimit"=dword:0000012d

Make a new text file and rename it to dnscache.reg. Then copy and paste the above into it and save it. Merge it into the registry.

Speed up internet by 20%

 

Microsoft reserves 20% of your available bandwidth for their own purposes like Windows Updates and interrogating your PC etc

You can get it back:

Click Start then Run and type "gpedit.msc" without quotes.This opens the group policy editor. Then go to:
Local Computer Policy
then Computer Configuration
then Administrative Templates then Network then QOS Packet Scheduler and then to Limit Reservable Bandwidth.


Double click on Limit Reservable bandwidth. It will say it is not configured, but the truth is under the 'Explain' tab i.e."By default, the Packet Scheduler limits the system to 20 percent of the bandwidth of a connection, but you can use this setting to override the default."
So the trick is to ENABLE reservable bandwidth, then set it to ZERO. This will allow the system to reserve nothing, rather than the default 20%.It works on Win 2000 as well.
