Hello,
I have a performance problem with udpcast :
- when I send data from one machine s to 2 machines r1 and r2 (all are connected with the same switch, all 1000M network card) with : udp-sender --full-duplex --min-clients 2 --max-wait 300 --interface eth0 --mcast-all-addr 224.0.0.1 --portbase 2232 --ttl --file /home/test udp-receiver --mcast-all-addr 224.0.0.1 --portbase 2232 --ttl 1 > /dev/null
I have a bit rate of 9.47 Mbps.
-when I send data from s to either r1 or r2 with the same commands, I obtain 945.55 Mbps !
I use the last version of udpcast (udpcast-20090920) and Debian Lenny.
Do you have any idea of why and how to solve this ?

Looks as if there was a 10 Mbps device connected somewhere to this switch.
Try switching on IGMP snooping (multicast support) on the switch, or switch off flow control on the troublesome port.
