High speed Pcap file

Mar 21, 2014 at 11:16 AM
I have high speed Pcap file, average traffic rate is 50 Mbit/Sec and when play this capture it take long time compare to the Pcap file length, what is the limit of this DLLs ?

Can you try and see what the bottleneck by checking if reading the file is the bottleneck or CPU?

While play this file CPU is 30%

Is the ovall CPU utilization on 30% or a single core? How many cores do you have?
Have you checked if just reading the pcap file takes a long time with sending the packets?

I have i7 with 4 cores.
Reading the file is quick, sending all it packet takes time, this file average rate is ~50 MBit/sec and average Packets/sec is ~9000

It could be the case that one of the cores is fully utilized.
You might need to parallelize your process so you can use more than one core.

Can you tell me what i need to do to test it ?

What exactly do you want to test?
If you have 4 cores, and you write a single thread program, and you see that ~25% of your CPUs are utilized, it means you fully utilize one core and probably need to parallelize your program so you can better utilize your resources.
