Protocol Buffer and JSON performance comparison

	Json	PB
Data structure Support	Simple structure	More complex structures
Data format	Text	Binary
Data size	So so	Small, JSON size of about 1/3
Analytic efficiency	So so	Fast, it's 3-10 times the JSON parsing speed.
Readability	Well, self-describing	In general, a. proto file is required, otherwise reading code is difficult to understand
Language support	Many Java/oc/php have a better library	General, official support C/java/python Oc/php has an open source library
Development cost	Low	Typically, you need to generate a proto class for each interface
Scalability	Same, add or remove fields can be compatible	Same, add or remove fields can be compatible
Security	No, self-encrypting required	Natural encryption, unable to decipher interface
Application	High visibility, good promotion	Slightly poor visibility, promotion in
