Recordings generate very large files – 10+GB/10 minutes of recording. As the files increase in size, they become more unwieldy .

tcpdump has a file rotate option. The idea is to split a tcpdump recording into multiple, serial pcap files, then have mongoreplay convert those into multiple, serial recordings which could then be played back as a single run.

In addition to the smaller files, the filter stage could be run on multiple files in parallel, saving significant time.
