I took a new ubuntu server with kernel 3.7.10
tried 1 M packet with 0.7 and the compiled version of 0.8rc
the 0.7 send 1 M packets and I receive 1 M packets
the 0.8rc send 1 M packets and I rceive only 150 000 .
Below is the command I use with the new trafgen.
What did I do wrong for only 1/8 packets arrive?

Maybe your application cannot cannot process so many packets?

Have you tried with:

  trafgen --in tcpsyn.cfg --out eth0 --num 1000000 --cpus 1

in order to use only 1 cpu on your server?

/home/netsniff-ng/trafgen/trafgen --in tcpsyn.cfg --out eth0 --num 1000000
      8 packets to schedule
    432 bytes in total
Running! Hang up with ^C!
