Excellent. Could you please provide me with a link to the conference, so I can produce it in my next activity report? > I did couple this with a streaming with OBS installed in a virtual > machine with a VNC access (so th only need for the operator is to have > an internet connection to launch OBS which is pre-configured, only one > button to press) I see. Hopefully we can have native support for OBS in Galene once they implement WebRTC, but I wouldn't hold my breath, the OBS team don't seem too interested in improving their networking stack. >> That's interesting -- perhaps I should do some profiling on 32-bit ARM to >> see where the inefficiency comes from. >>=20 > I suspect this is a sum of things.

It could also be due to a single hotspot -- perhaps the crypto (the RPi doesn't do AES in hardware), it could be slow I/O, or it could be the locking implementation that is different on 64- and 32-bit. I've got a 32-bit ARM board lying somewhere (a Beaglebone, thanks Dave), but it doesn't have Ethernet, so it's tricky to test. -- Juliusz
