Internet Explorer performance is dependent in part on the number of simultaneous
connections. One connection / one element can be downloaded – this includes
graphic elements. Each element on the page has to be downloaded. If a page is
only html text, the default number of connections available to IE, 4
connections, is adequate. What if the page has buttons, lines and lots of other
graphical elements. The number of elements that can be simultaneously download
is limited to 4. You can experiment with the the number of connections for IE
with the following registry hack. Milage may vary. Experiment to see how it
works for you.
Hive: HKEY_CURRENT_USER
Key:
Software\Microsoft\Windows\CurrentVersion\Internet Settings
Name: MaxConnectionsPerServer
Type: REG_DWORD
Value: 20
Name: MaxConnectionsPer1_0Server
Type: REG_DWORD
Value: 20
These values will not exist. If you are going to experiment, I would create
the values and increase the value by 5 or 10 until you see no improvement. Pick
complex pages to experiment with and don’t forget that pages are cached.
