nping: bitrate bug

[Мамаев Антон Владимирович <mamaev.anton () itmh ru>]

Good day.

I use nping for generate traffic with given rate. I need send 12mbit/s 
traffic ipv6:

nping -6 XXXX:XXXX::2 -e eth3.3352 --tcp -p 5032 -HN --data-len 1358 
--rate 1104 -c 662739

Send 662739 packet with payload 1358 byte and rate 1104 pps: 1358 byte * 
8 bit * 1104 pps ~ 12mbit/s

However, i see rate much more 12 mbit/s:

avm@avm:~# nping -6 XXXX:XXXX::2 -e eth3.3352 --tcp -p 5032 -HN 
--data-len 1358 --rate 1104 -c 662739

Starting Nping 0.6.01 ( http://nmap.org/nping ) at 2012-10-08 15:43 YEKT

Rx time: 2.43267s | Rx bytes/s: 0.00 | Rx pkts/s: 0.00
Nping done: 1 IP address pinged in 2.43 seconds

I see bitrate ~ 488 mbit/s!

Probably, there are restrictions this program?

Best regards,
Mamaev Anton.
