Re: Good performance? Scalable?
So says someone who either hasn't used Java since 2000, or hasn't updated their learning since then. Java's performance is not matter for subjective opinion, it can be measured directly.
Java is not as fast as C++ for bare algorithm implementation comparison. But it is NOT "miles slower" and the difference in speed between Java and Ruby is far greater than the difference between C++ and Java.
I speak not just as a programmer, but one with experience in the world of competitive coding contests where you are given a limited time for your code to process input data and return a result, where language performance is a big deal. Rather than quoting middle-management "I read Java was slow because it's interpreted" levels of misinformation.
