This question: Viability of using Java for parallel processing of parsing large (500Kb) HTML pages got 6 downvotes within a couple of minutes, and is now closed.
I guess the main contributing factor was that the title reads like a "x vs. y" question: is Java faster than PHP for parsing some massive XML files?
However, what the OP really wanted to know is whether Java has some built-in characteristics that make parsing large amounts of XML in it inherently faster, like threading. He appears to know what he's doing and he's unhappy about his library's overall performance.
I tend to think that's a fair question and shooting it down like this was a little premature. Or was it? Is it too broad either way? How should it have been put to have a better chance?
Either way - what should the OP do? I guess at -6, the question is not really salvageable. He should definitely add some stats to beef things up. Anything else? Was the question rightly downvoted and closed? Should they open a new one?
Should this be asked on Programmers instead?
