Scapy speed up sniff performance

I have a python script using the scapy 2.4.3 sniff() fuction, running in a thread:

sniff(iface=self.iface, store=0, filter="(ip and not src net %s) and (udp dst port %s)" % (self.ip_src, str(self.dport)), prn=self.handle_someip_packet)

It came to my attention that the execution of this sniffing thread is take too much time.

I would like to set the conf.layers.filter([UDP]), but I get the error: AttributeError: 'LayersList' object has no attribute 'filter'

What am I doing wrong?

Any other ideas to speed the scapy sniffing?

Thanks in advance,

You are probably using an older version of scapy without realizing. Try using 2.4.4rc2 (pip3 install scapy --pre)

You can check the version using scapy.__version__
