Receive Tests / CPU Usage / Firefox vs Chrome
Posted: Sun Apr 30, 2017 10:50 pm
Recently performed a "receive only" test and compared CPU usage using Firefox and Chrome browsers on a Dell Optiplex 580/Windows10/Dualcore AMD@3.0Ghz. Results indicate CHROME requires much lower CPU power than FIREFOX. This could be useful information if your computer is max'ing out on CPU power.
FIREFOX_____________PreBroadcast Video(MoTab)___ Broadcast Video(Joseph Smith)
CPU %----------------------------73 %------------------------------------80 %
Highest Bitrate------------1500 kbps-----------------------------1320 kbps
VideoBuffer Size---------->270 Secs-----------------------------60-70 Secs
AudioBuffer Size-------------60 Secs------------------------------60-70 Secs
CHROME_____________PreBroadcast Video(MoTab)___ Broadcast Video(Joseph Smith)
CPU %----------------------------47 %------------------------------------57 %
Highest Bitrate------------1500 kbps-----------------------------1320 kbps
VideoBuffer Size---------->270 Secs-----------------------------60-70 Secs
AudioBuffer Size-------------60 Secs------------------------------60-70 Secs
I think it would be helpful if the Portal used "receive test" videos of the same bitrate, encoding, & buffer size that is used when receiving a stake conference webcast. Presently there is no option to do a receive test at 2200kbps (the Vidiu HD setting).
Also, the Prebroadcast MoTab audio is compressed, consequently it "sounds" louder than the audio produced (without compression) at a stake conference. As a result, you cannot use it to set the volume levels before a stake conference begins-if you do then you will probably have to raise the level once the conference goes "live".
Using "test" video/audio that has the same characteristics and bitrate ranges as stake conference video/audio is important when troubleshooting/testing/validating and gaining a confidence level for your equipment - especially at the higher bitrates.
I REALLY appreciate having the present "testing" ability and use it often - these are just suggestions to make the portal a little better.
