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
