Internet Speed

Those of us fortunate enough to have fast internet connections (cable modem, DSL, etc.), the following registry tweak allows more concurrent HTTP connections while downloading a web page. Each item on a web page requires a separate HTTP "Get", so if your connection can handle more concurrent connections, you can "Get" more items downloading at once. This is what to do:

• Create a new plain text file and call it Tweak.reg.
• Highlight the text below and press CTRL+C to copy it:

   

  REGEDIT1

   

  [HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionInternet Settings]
  "MaxConnectionsPer1_0Server"=dword:000000a
  "MaxConnectionsPerServer"=dword:0000000a

• Paste it into your new text file by pressing CTRL+V.
• If you decide to make your own, make sure everything one the line that starts with "[HKEY_CURRENT_USER….Internet Settings]" is on one line. Also make sure that there are no blank trailing spaces, and that there is one carriage return after the last character in the text you paste.
• Right click on the file. From the context menu choose Merge. Wait a few moments. Remember to delete the REG file when you’re done.

Speed up Windows Explorer and network browsing by stopping automatic shares in "My Network Places"

By default, Windows 2k/XP/2k3 tries to read icon information from shortcuts in the "My Network Places" folder, accessing remote files on the network, and causing a very slow system response. Every time you open a file in a remote shared folder, or a file via a UNC name, Windows will automatically add another shortcut to "My Netowork Places", making the problem worse with time. To resolve this:

Navigate to:

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorer and add a new DWORD value:

NoRecentDocsNetHood=1 (set it to 1 to disable remote shared folders from being added to Network Places).

Depending on your OS, it might also be possible to modify this by accessing the Group Policy Object Editor. To use this method to achieve the same effect:

– Go to Start > Run > type: gpedit.msc

–  In the GPOE, navigate to: User Configuration > Administrative Templates > Desktop > Enable "Do not add shares of recently opened documents to My Netowrk Places"

If you increase the number of network redirector buffers it may considerably increase your network throughput. Each extra execution thread that you configure will take 1K of additional nonpaged pool memory, but only if your applications actually use them.

To configure additional buffers and threads, edit: HKEY_LOCAL_MACHINESystemCurrentControlSetServicesLanmanWorkstationParameters Modify or Add Value of type REG_DWORD for:

MaxCmds=dword:00000064 – range is 0 – 255 and the default value is 15. Set to a higher number, try 64 for starters.

MaxThreads=dword:00000064 – set to the same value as MaxCmds.

MaxCollectionCount in the same key is a DWORD buffer for  character-mode named pipes writes. You might want to increase it from te default 16 as well, its’ range is 0 – 65535.

In higher latency Network environments, delays may be encountered with the default request buffer size (4356 decimal). The range of this parameter is 1024 – 65535 bytes. Testing has shown that, in most standard Ethernet environments, 16384 (decimal) is a better choice, if memory is available. This tweak only applies to LANs, and helps with slow browsing of large directories.

To change this setting, edit:

HKEY_LOCAL_MACHINESystemCurrentControlSetServicesLanmanServerParameters and Add Value name SizReqBuf as a type REG_DWORD, increase its (decimal) value to  16384 or even higher and restart the computer for changes to take effect.

Here is the MS KB Article 320829 that describes the procedure as well.
