Thank you for the information.
Looking at it through Wireshark as well though - it is many files as
compared to one big one (if that is what you are after i suspect).
There are some info notes too - "[Packet size limited during capture:
HTTP truncated]".
Is that the pcap extracted from Moloch or the pcap captured on the
sniffing interface where Suricata runs?
Couple of other things you may need to confirm/look at : if you have
all NIC offloading disabled and the default packet size in
suricata.yaml

Thanks
