More Internet Bandwidth
How to grab more internet bandwidth so internet runs faster.
To increase Internet Explorer bandwidth do the following click on Start > Run and type Regedit, then go to the following area --
HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENT VERSION\INTERNET SETTINGS
Right mouse click in the right hand window move mouse on to new DWORD value and add MaxConnectionsPerServer and make the value 8 decimal then Right mouse click in the right hand window move mouse on to new DWORD value and add MaxConnectionsPer1_0Server make this value 6 decimal and close RegEdit now you can run
Internet Explorer with out rebooting and downloads and new
pages will be faster.
NOTE: the first entry was mispelt in the article.. should be MaxConnectionsPerServer.. It is corrected in the text above. Also... I set both these settings to 16 on my home box (WinXP, IE6) and it was hellaciously speedy. Works under Win2k as well. Use with caution.. caution for what I dunno but it sounds good.
