Surprisingly not. From the tests I've done, json_encode is faster than 
serialize for most things (serialize only beat json_* for very small 
arrays), and the same for json_decode/unserialize.

Personally, I prefer json_encode/json_decode because I tend to be 
storing arrays instead of actual objects (or stdClass objects anyway), 
and the speed is worth it for me (I'm storing 10k+ objects).
