Performance of gzipped json vs efficient binary serialization
<p>JSON and Gzip is a simple way to serialize data. These are widely implemented across programming languages. Also this representation is portable across systems (is it?).</p>

<p>My question is whether json+gzip is good enough (less then 2x cost) compared to very efficient binary serialization methods? I'm looking for space and time costs while serializing various kinds of data.</p>
