Performance

Currently I am doing the profiling to a piece of code. During the profiling, I discovered that this very method call,

Class<T>.isAssignableFrom(Class<?> cls)

takes up to quite amount of the entire time.

Because this is a method from reflection, it takes a lot of time compared to normal keywords or method calls. I am wondering if there are some good alternatives for this method calls?
