A good memory is better than a bad writer. 48-java Interceptor-jdk with dynamic agent and cglib efficiency comparison (3)

The class of the dynamic proxy that comes with Java must implement an interface, and it is said that the use of reflection is not very efficient. So the Cglib was born.
The use of Cglib to implement dynamic proxy, completely non-agent class must implement the interface constraints, and cglib based on ASM bytecode generation framework, using bytecode technology to generate proxy classes, in theory, than using Java reflection efficiency is higher.
So what's the efficiency of this run, when we test it?

4. Table of Operational efficiency

The efficiency of Cglib's dynamic agents seems to be less efficient than Java's own. This may not be the same as the situation we have heard.

5. Other
Before putting Cglib in Java's own proxy method, the data situation is basically the same as above.
