Speed Up Network File Copying While Playing Audio in Windows Vista SP1
Windows Vista (SP1 in particular) provides network throttling to avoid audio lagging while you are transferring files on the network. This is a very common issue with Windows Vista that when you are playing some audio and transferring data on the network, either your playback be affected or your network would be down to painfully slow.
There are so many other ways that are very affected than Vista’s networking throttling tool. You can add up a dedicated NIC (“Evga’s killer xeno pro’’, in particular, it works as a co-processor that manages network traffic) that would take care of networking, would make a dent on your wallet (costs around $100). On the other hand you can buy any Creative’s sound card that features creative’s exclusive technology, “Alchemy”. Using these sound cards, your multimedia would not be affected by network traffic.
But the best and free (but risky) way is amending the throttle networking index value in registry, sounds risky but provide you with free way to get rid of slow network speed, while using multimedia applications. To do this all you need to do is, got to Start Menu search bar (can also use RUN) and search for “regedit.exe”, and browse for the following key:
“HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionMultimediaSystemProfile” (excluding “” marks)
Once you found it, on the right hand side you will see “NetworkThrottlingIndex” caption, open it by clicking, a dialog box will open through this you can change the value for throttle.
The value can be changed from 1 to 100 (1% to 100%), but it is better that you limit it to 70. You have to reboot every time you make changes in it. It is also good to check for the value that suites your needs. The value 70 may work well only for wireless network, not for gigabit network.
