The first is that Scapy is not designed for fast throughput. It is written in Python, has many layers of abstraction, and it is not very fast. Do not expect a packet rate higher than 6 Mbs per second. Because of these layers of abstraction, and because of being written in Python, it may also require a lot of mem- ory. When dealing with large amounts of packets, packet manipulation becomes uncomfortable after about 216 packets. Scapy is stimulus-response-oriented. While you could do it, handling stream proto- cols may become painful. This is clearly an area of improvement. Yet, for the moment, it is possible to play with a datagram-oriented protocol over a stream socket managed by the kernel. You can easily design something that sniffs, mangles, and sends. This is exactly what is needed for some attacks. But you will be disappointed in terms of performance or efficiency if you expect Scapy to do the job of a router. Do not confuse Scapy with a production mangling router that you could obtain with Netfilter. Sursa: Security Power Tools pagina 139.
