Streaming a contiguous file through a compression device is not
indicative of real Internet traffic. Packets of various application are
interleaved within flows. The Calgary files may be a good benchmark for
comparing different compression algorithms in a stateful environment;
however, they do not represent the stateless environment that the
Internet represents.
