Tcpreplay Performance Database

This is a public database of real world performance numbers of running tcpreplay on different hardware & operating systems. The goal of this database is to collect information from real users so that the community can answer questions like: "How fast can tcpreplay go?" and "What hardware works the best with tcpreplay?".

Database

Please fill out as complete as possible! As a base-line, please use the following tcpreplay options: -qKt -l 100 -i <nic> <pcapfile>

Note 1: Very large and small pcaps tend to skew the results very badly. Your test run should run at least 30 seconds; if not, increase the loop count. If your pcap is too large it won't fit in RAM which will also slow things down a great deal.

Note 2: It is important that your system is plugged into a network and has link! Most operating systems will claim the packet is "sent" but if there is no link, the network card will drop the packet which will skew the results.

Note 3: The capinfos tool is provided with  Wireshark will tell you the average packet size

Note 4: Be sure to read how to tune your operating system for high performance with tcpreplay
