> It would be interesting to see the effect of compressing the segments within the tar
files with a sufficiently effective and performant compression algorithm:
> * Can we increase overall throughput by trading CPU for IO?
> * Can we scale to bigger repositories (in number of nodes) by squeezing in more segments
per MB and thus pushing out onset of thrashing?
> * What would be a good compression algorithm/library?
> * Can/should we make this optional? 
> * Migration and compatibility issues?
