[LARTC] kernel udp rate limit

[LARTC] kernel udp rate limit

[Sebastian Muniz]

Hi List.
First post, be gentle please.
Is there any limit in the linux UDP rate?

I am using linux kernel 2.6 and iperf to measure bandwidth
between two endpoints connected by 100 Mbits ethernet.
Running (as root) iperf -u -s
and iperf -u -c always gives me 1.05 Mbits/seg
even when runned in the same machine.
Can somebody clarify this?

Thanks in advance.
Sebastian

iperf --help

Client specific:
  -b, --bandwidth #[KM]    for UDP, bandwidth to send at in bits/sec
                           (default 1 Mbit/sec, implies -u)

If you wanted to push 5 Mbit/sec you would say "iperf -c 1.0.0.1 --udp
--bandwidth 5M"
