A simple benchmark of synchronization

Test.java

public class Test {
    public static void main(String[] args) {
        int value = 0;
        long now = System.currentTimeMillis();
        for(int i = 0; i < 1e8; i++) {
            value++;
        }
        System.out.println("Unsynched version took " + (System.currentTimeMillis() - now) + "ms");
        Object syncher = new Object();
        now = System.currentTimeMillis();
        for(int i = 0; i < 1e8; i++) {
            synchronized(syncher) {
                value++;
            }
        }
        System.out.println("Synched version took " + (System.currentTimeMillis() - now) + "ms");
    }
}
