Yep I agree. Java isn't slow if you build a trivial application. Or an HTTP server. Or something for batch processing. Or if you're a masochist working around performance issues until you reach about ~C level of performance and performance "robustness". The problem is what Java encourages you to do. And I didn't want to single out a language; Java is just one that I revisit from time to time and I'm always astonished how awkwardly hard it is to do the simplest things in a straightforward (and CPU-efficient) way. And yes, there are a lot of slow C++ programs, and even slow C programs. There's just a clear tendency for C programs to be faster and more responsive.

> tendency for C programs to be faster I was involved in a massive rewrite of a website from C to Java a while back. One coworker observed that, when they were coding in C, it took a lot longer to get anything working, but once you did, it was pretty solid: C had a tendency to just crash if anything was wrong, so you'd work for quite a while before you got something that didn't crash consistently. Java, on the other hand, allowed you to get something working (that is, running without crashing) much quicker: but the things that were out of place were still there, they just caused harder-to-find problems that were much more likely to become customer-facing before they were caught.
