Many modern frameworks (Spring, Hibernate) provide very nice dynamic behaviors with use of Java dynamic proxies, but what's the exact performance cost associated with it? Are there public benchmarks available for Sun JVM?
Here is a piece of C++ code that shows some very peculiar behavior. For some strange reason, sorting the data miraculously makes the code almost six times faster:
#include <algorithm>
#include <ctime>
#include <iostream>

I am using this code to convert a Set to a List:
Map<String, List<String>> mainMap = new HashMap<>();
for (int i=0; i < something.size(); i++) {
Set<String> set = getSet(...); //returns …
