STL does have a few tarpits and once you know which classes to avid, it's smooth cruising. I recommend Scott Meyer's Effective C++ books if you want to learn how to avoid a lot of C++ performance black holes: http://www.aristeia.com/books_frames.html
Yes, the choice of a C++ compiler does make some difference in algo heavy functions/methods but the art of writing high performance C++ programs has a lot more to do with overall design (which is sometimes C++ specific) and your programming style. I left C++ programming but if that's your cup of tea, look into Meyer's books. They're the best.
Java guys care because of Java's history: it was always slower than compiled languages and Java dev got a lot of crap for not having fast runtime. That's all history but there's still a ton of people out there who refuse to download Java-based programs because of 'slowness' myth.
