Je ne savais pas où mettre ça : pb perf en UDP... alors je le colle ici
Applying the Microsoft HotFix KB2685007 on Windows 7
Windows Server 2008 R2 and Windows 7 are both affected by
[#ff0000]a UDP issue[/#ff0000] which restricts maximum throughput of clients connecting to a storage server for video streaming.
Microsoft has issued a HotFix which is targeted to Windows Server 2008 R2, but can be applied to Windows 7 clients, and results in an approximate 45% maximum speed improvement.
The Microsoft Knowledge Base article (
http://support.microsoft.com/kb/2685007/EN-US) is written from the perspective of Windows Server 2008 R2 and not Windows 7; hence it is not possible to follow the procedure given by Microsoft, but using the modified procedure below you can improve system performance.
To download the hotfix, you must supply a valid email address, to which the link will be sent.
Follow the instructions to download the hotfix. Do not click the “Fix it for me” link; this does not work on Windows 7.
Instead, run the file named 447595_intl_x64_zip.exe and specify a path to a location on the client system.
Navigate to that path and run the file Windows6.1-KB2685007-x64.msu, then use the following procedure to create a new registry value.
To manually create a new registry value:
1. Click Start, and type regedit in the Search programs and files box, then press Enter. If prompted for an administrative password, enter it.
2. Locate and click the following registry sub key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BFE\Parameters\
3. On the Edit menu, click New, then click DWORD Value.
4. Type MaxEndpointCountMult, and then press Enter.
5. Right-click MaxEndpointCountMult, and then click Modify.
6. In the Value data box, type 10 (for Base, select Decimal), and then click OK.
The MaxEndpointCountMult registry value is a multiplication factor that applies to the default scavenge value of 15,000. You can set the MaxEndpointCountMult registry value from 1 to 50,000. The recommended value is 10.
7. Exit the Registry Editor.
8. Reboot the client system.
