Thank you for the link. Damn is slow this CPU.

Not comparing to other system but comparing to the peoples
experience/knowledge of this mailing list. I was looking for an answer
like: yes, you should expect more from those 4x2 cores at 3GHz, you
probably configured something wrong...

I lack of experience in this field so I had to ask. Maybe I was
expecting too much from that hw.

All 6 streams are sending UDP to ffserver. FFserver is configured as I
posted in previous mail, all 6 streams have the same config:
/usr/bin/ffmpeg -i udp://239.100.0.0:1234 
http://172.31.254.210:8090/stream001.ffm
/usr/bin/ffmpeg -i udp://239.100.0.1:1234 
http://172.31.254.210:8090/stream002.ffm
/usr/bin/ffmpeg -i udp://239.100.0.2:1234 
http://172.31.254.210:8090/stream003.ffm
/usr/bin/ffmpeg -i udp://239.100.0.3:1234 
http://172.31.254.210:8090/stream004.ffm
/usr/bin/ffmpeg -i udp://239.100.0.4:1234 
http://172.31.254.210:8090/stream005.ffm
/usr/bin/ffmpeg -i udp://239.100.0.5:1234 
http://172.31.254.210:8090/stream006.ffm

Now, that I've checked the quality of picture on a larger TV set it
looks, that I have to post another thread.
