Compression on the wire

How it behaves

One input on the horizontal axis, the others held fixed.

Worked examples, recomputed

Every number the mechanisms quote for this relationship is recomputed from it, so none of them disagrees with it.

• 1 GB at 125 MB/s → 8 s
• compressed at 125 MB/s → 5.3 s
• 1 GB at 12,500 MB/s → 0.08 s
• compressed at 12,500 MB/s → 2.7 s

Where it appears

Each mechanism states it in its own names. The general symbol each name stands for is shown with it.

• Data Movement

  How do records cross between two systems that have independent rates, independent availability and independent lifetimes, and what are you willing to lose when the assumption underneath the crossing breaks?

  $$\text{compress}+\frac{\text{compressed size}}{\text{link}}+\text{decompress}\text{vs}\frac{\text{size}}{\text{link}}$$
