Of course pretty much any serialization in any language can serialize faster than you can write to network. But if you take 50% of a CPU to fill the network vs 5% of a CPU to fill the network, that drastically impacts how much other work you can be getting done in other tasks at the same time. Although many workloads are IO bound, many are not. For example, if you have a lot of RAM available for HBase, it will become CPU-bound pretty quick as you are primarily hitting cached data. -Todd -- Todd Lipcon Software Engineer, Cloudera
