Thank you for your quick response:
I run the 3.4.3-2 version. Installing the latest stable version didnt work.
user@Sender:~$ svn co svn://svn.synfin.net/tcpreplay/branches/3.4 tcpreplay-3.4
svn: Can't connect to host 'svn.synfin.net': Connection refused
Downloading the tar.gz file and compiling from source didnt work:
checking for libpcap... configure: error: Unable to find matching library for
header file in /usr
The packets specified and the packets truly sent differ a lot.
In the beginning:
Next transmit will be at 326 pps at 2013_03_21 00:01:09
Actual: 97800 packets (5868000 bytes) sent in 305.52 seconds
Rated: 19206.6 bps, 0.15 Mbps, 320.11 pps
After a while:
Next transmit will be at 299800 pps at 2013_03_21 03:17:55
Actual: 6826050 packets (409563000 bytes) sent in 138.54 seconds
Rated: 2956279.8 bps, 22.55 Mbps, 49271.33 pps

Attempted packets: 6826050

I send the same ARP broadcast packets.
