Slow IE Upload Speeds?

Recently I ran into a problem with IE 8 at work. Yes, that can be a wide range of problems but I found something a bit more specific than that.
We recently implemented a Share Point site and I noticed when doing speed tests for uploads of large files through IE, the speeds were quite a bit slower then the upload speeds in Chrome and Firefox. I thought that this might be a problem being that most of our users are going to be accessing the site through IE 7 or IE 8. I did a lot of searching and couldn’t really find much of anything. Most articles are about either speeding up torrent downloads or disabling plugins and things of that sort to speed up your browsing speeds in IE.
Then I found this site: http://support.microsoft.com/kb/329781
This article talks about changing the “Socket Send Buffer Length” in the registry to give IE more buffer space to upload files. The article gives the following steps in order to resolve the slow upload issue (as always back the registry and be careful when editing the registry):
- Start Registry Editor (Regedt32.exe)
- Locate and then click the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings - On the Edit menu, click Add Value, and then add the following registry value: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 = 1638424-KB Buffer = 2457632-KB Buffer = 3276840-KB Buffer = 4096048-KB Buffer = 4915256-KB Buffer = 5734464-KB Buffer = 65536 - Quit The Registry Editor
- Reboot the computer or Log-Off and Log-In again
In these steps I found the sweet spot for my machines to be 40-KB. You can setup the higher buffer sizes but I didn’t really see any benefit to the higher buffer sizes. This fix really did increase the upload speeds to be about the same as Firefox or Chrome.
Give it a try and see for yourself!
