Re: kernel 2.4.2 network performances

Hi again. I've written my own test program, and I get 12M throughput. I used a packet size of 1024 Bytes. Smaller packages seems to result in less throughput. There was no load on the machine I tested on. Does the throughput get better is there is a lot of stress on the machine? (eg. compilin

Hi Jerome. As Mr. Hafting says, is seems that there is a softirq missing somewhere. If this is the case, it should help to make some add some systemcalls in your program, since a softirq should happen at every system-call exit. Try adding: getpid(); in the innermost loop, and see if i

kernel 2.4.2 network performances

2001-03-15 Thread Jerome Tollet
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. Unde
