As I've said before, accessing the pcap_stats() function loses packets.  So
if you are sitting there pounding on refresh to see what you are losing,
well, you are going to be losing more.

Hi All,

I've just upgraded to Ntop-3.1 and am seeing much worse performance than
3.0.


Dropped Libpcap packets are not very high, I'm using PF_RING which fixed the
same issue under 3.0

Can anyone help ?
