Scaling across multiple machines is a completely different problem than pushing a single machine to the limit, with completely different constraints. Once you move beyond a single CPU and you can tolerate higher latency then languages like Java start to become more viable. When you need maximum performance and minimal latency from a single machine C++ is still the first choice and the number of high-performance apps written in C++ vastly outnumbers those written in C. Check high frequency trading for another example.
