We're still working at the performance, this is the current ongoing
work. I have not understood if we not use more or less CPU with
respect to before
We will add the demon mode.

Hi all,
Updating this, just downloaded the last svn one, now it goes faster,
but still crashing but without saying the Segmentation Fault.
Now it uses at least more CPU, like 30-40% of total.
Thank you,

Hi all,
Just installed Ntopng on a ubuntu server 64bits.
I'm getting tons of [NetworkInterface.cpp:268] WARNING: IP fragments
are not handled yet!
and [NetworkInterface.cpp:268] WARNING: IPv4 fragments are not
handled yet!
Is it possible to run ntopng in daemon mode like old ntop?
Can those messages be ignored?
When I start it, starts working well, but suddenly it start going
really slow, only reading 2Mbps, 19Mbps, 0Mbps, 2Mbps... then
segmentation fault. I It happens in less than a minute or can be
working for 5 o 6.
Htop sais ntopng is only using 3% cpu in 2 threads (total 6%)
Luca, I can give you access to the machine for testing if you want.
Also, Im getting like 65% of traffic as unknow.
Thank you,
