  • On-board memory helps mitigating traffic spikes/bursts and reduces the probability of packet loss during capture.

** Pcap chunk mode allows the NIC to deliver many packets in one block to the application, instead of packet-by-packet. Thanks to chunk mode, the application (in particular n2disk) can significantly reduce the CPU load when dumping packets to disk. Please note that in case of index creation while dumping packets, n2disk still needs to iterate packets; even in this case chunk mode can help as it is usually more efficient than packet mode. * This needs to be tested or it is not applicable due to feature limitation. ** Supported on some adapters
