write_to_file() calls fwrite(), which puts stuff in a buffer before writing to the file in the sense of "calling write() or WriteFile()).  Would adding another layer of buffering atop the standard I/O library buffering make a significant difference here?  (libpcap, as used by, for example, tcpdump, makes multiple fwrite() calls per packet written.)
