Comment on Many times faster (de)compression using multiple processors.parentComments−igorhvrOP14yBy resources I meant wall-time, mostly - what I am optimizing for (I move >200GB zfs snapshots around a lot..). I did not pay attention to memory, specifically - in that light I updated the side note.What else did you find odd/wrong?−alecco14yYou don't mention ratios. Better compression becomes asymptotically/exponentially harder when it gets close to the optimal code size.Thanks for the shout out. BTW Matt's benchmarks are for all major compression engines, not only bzip2.
