Well, my colleague may have found the problem. It seems that it is a kernel configuration since 2.6.17 that is in cause. On my machine, and those of my colleague, setting net.ipv4.tcp_rmem works fine. I've not yet tested on other machines that had similar problem ...
To set this configuration, run : sudo sysctl -w net.ipv4.tcp_window_scaling=0 Or append "net.ipv4.tcp_window_scaling=0" in /etc/sysctl.conf It seems (on french forums) that this configuration coulod affect local wide transfers, in this case, configuration of kernel < 2.6.17 is "net.ipv4.tcp_rmem=4096 87380 174760".
