Increase DNS Cache

Increase DNS Cache In Windows Vista / Windows 7 For Faster Web Browsing

Here's how:

・Click on Start -> choose Run -> type in regedit -> press ENTER.
・Locate and then expand the following registry subkey:


・Go to New > DWORD (32-bit) Value.
・Name it as CacheHashTableBucketSize
・Double-click into it and enter the value 1 (in Decimal)
・Also create the following DWORD values with the following values also in Decimal:

NegativeCacheTime = 0
CacheHashTableSize = 384
MaxCacheEntryTtlLimit = 64000
MaxSOACacheEntryTtlLimit = 301

To make the changes to take effect, flush your Windows DNS cache by issuing the command ipconfig /flushdns at an elevated command prompt (run CMD as administrator). The command will flush your DNS cache — all the entries, both positive and negative, will be flushed — and it will be empty until you start visiting Web sites.

Restart your computer for the changes.
