Further fine tune Internet access speed: Tip on improving DNS

Internet browsing is such an exciting and easy experience now a days that

we have almost forgotten the amount of work that goes behind the scene to

make this all happen. We only feel bad if we can't find something easily or

have to wait for a long time (I have heard many people saying WWW stands

for world wide wait not too long ago!!!) Well with changes in technology

and falling prices we have far better hardware and software to do this job

but fruits of fine tuning have always been great and would continue to

remain so. One of the things that should happen before Internet connection

would go through is DNS resolution.DNS stands for Domain Name Service. Even

though XP does a fine job of handling DNS resolution, you may still gain by

increase the DNS Cache size. To do this you would have to add following

entries in registry. Save what is written below in say "dnstuning.reg" file

and import it in REGISTRY but opening registry editor and going to IMPORT

option from top menu.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters]

"CacheHashTableBucketSize"=dword:00000001

"CacheHashTableSize"=dword:00000180

"MaxCacheEntryTtlLimit"=dword:0000fa00

"MaxSOACacheEntryTtlLimit"=dword:0000012d

Fine tune Internet connection speed: Tip on changing QoS parameter.

This tweak deals with QoS parameter manipulation. There have been some

confusion as to what can be achieved in real terms by changing the QoS

parameter. Microsoft has finally released an article correcting describing

the behavior of QoS parameter. I am providing a link to Microsoft web site

knowledgebase article

In

brief though, this tweak would only work on QoS aware programs and rest of

the programs would simply ignore them. Networking Quality of Service (QoS)

refers to a variety of techniques that prioritize one type of traffic or

program when these operate across a network connection rather than relying

solely on "best effort" connectivity. Please click on how to change QoS

parameter article using Group Policy Editor

(GPEDIT.MSC).By default, programs can reserve up to an aggregate bandwidth

of 20 percent of the underlying link speed on each interface on an end

computer. If the program that reserved the bandwidth is not sending enough

data to utilize it completely, the unused portion of the reserved bandwidth

is available for other data flows on the same host. This default parameter

can be changed.
