[streaming] Re: Increasing number of video streams on VLS

[Vince Phan]

Yes, I did the test on two machines already.
On Linux Debian it took 2 thread/stream each ~5-8% of CPU usage, total
of 10-16% per stream.
On Window2000 it took 11% of CPU usage.

Your 0.5% result really excited me because my PC should be able to do at
least 40 streams.

It would much easier that I could see your vls.conf file.
I wonder are there any special settings require to achive this rate or
perhap it could be my config is stuffed.

Thanks.

Are you really sure of your tests ? What operating system are you
running ?
I am using a PIII 933MHz, 128MB under Linux Debian and vls never uses
more than 0.5% CPU

If the stream is a TS file, VLS won't process it at all.
