Hi,

i replayed a small dump file (about 30 packets) using -l 10000 at different 
speeds (2000, 4000, 8000 and 15000 pkts/s) using tcpreplay 2.x and tcpreplay 
3.0.betax
Both, tcpreplay 2 and 3, displayed the message

processing file: /home/lothar/net/localhost.dump

on stdout.

Tcpreplay 2 writes this message once, while tcpreplay 3.0 writes the message 
each time the dumpfile is processed. This behavior results in an huge amount 
of messages printed to the screen with tcpreplay.
The more packets per second you replay, the more busy tcpreplay gets printing 
these messages.

Whereas tcpreplay 2 had no problem to send out all packets at 15000 pkts/s, 
tcpreplay 3 already got problems at 4000 pkts/s because it was so busy 
printing its messages.

I think it would be a good idea to get the tcpreplay-2 behavior back. Is that 
possible for the next beta or the final release?

Best regards,
  Lothar
