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.
