BGU, I think there are two issues here but they could be related. 1. Network speed drops from 270 to 15Mbps 2. Stops, skips and buffering.
The results are interesting but unfortunately do not provide nay insight into the problem. Test 2 & 3 are basically the same test just using Recorder or wavin2cmd to copy audio data to a file. If there was a difference in the network speeds then wavin2cmd.exe could be blamed. Since both tests have the same result all that can be said is that capturing audio while running SC seems to affect Network performance. To see if SC has any affect on the problem - you could run the "Recorder" test with a Browser playing a network radio station and without SC running and check to see if network speeds changes between Recorder running or not. Even though network goes down to 15Mbps - this is still lots of capacity for SC - so there must be another reason for the skips - excessive CPU usage is one possibility. I have two theories 1. Security software - it is checking all "network" activity and the audio capture will look like network traffic and so it is slowing whole system down. The test is to disable all security s/w and see if there is a change. 2. USB network driver - the USB network adaptor has put a lot of code in the kernel network driver and not a lot in the adaptor so that it can be updated to handle changes in the 802.11n standards. Anything that operate at Kernel level (e.g. audio capture) will take away CPU time from the USB network driver and so affects performance. Test - use onboard LAN connection and then a "Normal" 802.11g USB and see if performance is affected. -- bpa ------------------------------------------------------------------------ bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=35718 _______________________________________________ plugins mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/plugins
