That's interesting! With setAccesible(true) java.lang.reflect is comparable to CGLIB on Java6:
java -client: Reflection: 260 ms (2.61) CGLIB FastMethod: 249 ms (2.46) CGLIB InvokeByIndex: 247 ms (2.43) Direct: 72 ms java -server: Reflection: 197 ms (8.38) CGLIB FastMethod: 186 ms (7.86) CGLIB InvokeByIndex: 198 ms (8.43) Direct: 21 ms > > BTW mina-sm looks excellent, very interesting design.
