    That's a good point. At 10x it's definitely too slow. Too bad, would have been too easy.

    I guess one could still consider some very cheap data specific delta compressions
    (I assume there's a lot of redundancy in a tracing stream with similar events
    occurring in a row or nearby) I used this technique successfully with large log files
    in the past and overall moving less data around ends up being cheaper.
