Do you find HTTP uploads to be terribly slow in IE? If so try this hack:
1) find this spot in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows
\CurrentVersion\Internet Settings
2) Add the following:
Value name: SocketSendBufferLength
Data type: REG_DWORD
Radix: Decimal
Value data: Buffer size that you want (in bytes)
Buffer size value options:
16-KB Buffer = 16384
24-KB Buffer = 24576
32-KB Buffer = 32768
40-KB Buffer = 40960
48-KB Buffer = 49152
56-KB Buffer = 57344
64-KB Buffer = 65536
Caution:You should only do this hack if you have a really good reason as the winsock send buffer was made small for a reason: http://support.microsoft.com/default.aspx?scid=kb;EN-US;214397
enjoy.
