[MULTICAST] PCs restoration

Post by guillaume80 » 01 Nov 2009, 16:52

Hello,

I have a problem with updcast.

On the source pc :
udp-sender -p "gzip -c" -f /dev/hda2
On targets pc :
udp-receiver -p "gzip -dc" -f /dev/hda2

Test On 3 targets pc :
Average output : 10Mbps
Estimate time : 20min

Test On 15 targets pc :
Average output : 1.94Mbps
Estimate time : > 1h

The man page of udp sender said that :
"Thus, sending to 10 destinations does not take more time than it would take to send just 2. "

However, not for me.
I must use the --broadcast option with udp-sender ?

Thanks for yours futures responses.
