| |
Hello, i have a problem with the network layer of linux kernel 2.4.2 I wrote a minimalist program which basically sends UDP datagrams over the network in an infinite loop. Under Linux 2.2.x, this program floods the network and my xosview prints that 12 MB/s are sent over my 100Mbit ethernet.
Under Linux 2.4.2, this program can't flood the network because my xosview (the same ;-) ) tells me that 4.6MB/s are sent over my ethernet although my cpu is not overloaded.
I think that Linux 2.4.2 limits the rate of packets sent over the network with some soft parameters. *Does anyone have any idea ? *Could someone explains me the new /proc/sys/net/core/{hot_list_length|no_cong|no_cong_thresh|mod_cong|lo_cong} parameters ? *Where could i see in the code this soft limits ?
Thanks for your help. Please CC me your response while i didn't subscribed to the mailing list.
