Great !!!
--nosync do the trick
But still a lot of re-xmits, ie
root@debian:~# udp-sender --file /dev/sda6 --interface eth0 -P 9000

Hi
Have you try to use "--no-sync" option?
I had a similar problem and i solved it that way. I think that udpcast has
change its default settings in any cases.

Hi
Sorry for my English.
I have been using udpcast (PXE or a custom Debian Live) over the past two
years (version 20100130) and I recently upgraded to the latest version (
20110710), the old version got a transfer rate of about 480Mbps, withfeww
reemissions (approximately 10 re-xmits) with the new and the same teams
involved does not exceed 43 Mbps. I tried to disable ipv6 (ipv6.disable =
1) but there was no difference.
If I use the udp-sender (20110710) with the udp-receiver (20100130)
recovered the rate of 480 Mbps.
How do I find out why the number of re-xmits increases significantly?
Thanks in advance

Hi again
It seems that with

we can recover behaviour preceding.

Hi
In fact, i'm testing this with a selfmade usb live linux distro, thus i did
the echoes before starting udp-receiver inside a script
#!/bin/bash
echo 513920 > /proc/sys/net/core/rmem_default
echo 513920 > /proc/sys/net/core/rmem_max
. /root/install/funcions
if [ $2 = "p" ]
then
desmunta_particio $1
imatge="$1"
modalitat=$(zenity --list $op_zen --column="Selecciona la modalitat de
compressió" "Sense compressió" "Compressió lzop"
"Descompressió lzop"
"Partclone")
elif [ $2 = "d" ]
then
