Java - System.out effect on performance

Question

I\'ve seen this question and it\'s somewhat similar. I would like to know if it really is a big factor that would affect the performance of my application. Here\'s my scenar

Answer 1

System.out.println()

is synchronized.

 public void println(String x) {
    synchronized (this) {
        print(x);
        newLine();
    }

If multiple threads write to it, its performance will suffer.
