Mwirigi - to process Mbps/Gbps payload data as fast as you're telling us you want, you may need a cluster or some other parallel distributed processing system which i don't think you have at the moment coz your question wouldn't appear on the list.. (and it's thus clear you can't be working with NSIS so it may take you time to get this going..) note also that unless your kernel is intentionally broken in special ways to bias fairness, your process would be quickly terminated as a memory/processor hog. 

So take my suggestion, first dump to file then process later.

@aki, am not intending to go to the hard bits, all i want is to process the payload for "scapy" which is an elaborate module on packet processing and then have scapy deal with everything else on layer 2 and layer 3. Both tcpdump, scapy and the cousins pcapy and impacket all utilize the pcap library which is a "C" library and is well tuned.

in short am just using other peolple's work to pull this one.

@Joe, sorry me too, I was bit confused there. Btw, you have chosen a huge challenge with decoding the raw data. I just went through some old docs,  The Byte Offsets/Bit Offsets in the Ip Hreader are crazy. And you have to do the same for UDP. I see where @Jonas come up with the word thread. Seems socket programming is processor intensive. This is quite interesting, hope you don't mind if I follow as a spectator. :-)

@aki, sorry i had got it all wrong, the saving to file was and is what i dont intend to todo
