[streaming] Re: Increasing VLS thruput

[Paul Rae]

I would love to know how you get this thruput!

We have a number of systems here ranging from 1Ghz P3 systems to several P4 systems, all with min 256mb ram, and the best we have been able to get is 2 - 3 streams (typically 2-4mb/s streams)

Are you streaming using VLS or VLC? And what distro are you basing it on? RH, Deb, other?

That's quite  strange. What's the  source of your  streams ? Is  the CPU
utilisation of ssytem or user type ?

I'm  currently streaming  1 DVD  stream  (8 Mbit/s),  3 satellite  Video
streams (4 Mbit/s each) and 25 radios (200 kbit/s each) from a Duron 900
MHz 256  Mo ram, and  CPU is still  40 % idle...  I managed to  stream 6
MPEG4 videos using VLC stream output on the same server before it became
overloaded. (the total bitrate was over 30 Mbit/s).
