Hmmm, this is not established wisdom and the glib "check the benchmarks" 
doesn't quite help.

Java has gotten on par with C and C++ for raw performance of "straight" 
code (numerics, I/O etc). I've seen such. Java seems to have issues 
involving layout control, which is an important influencer of 
performance in computing nowadays.

Clearly the Java community has amassed a nice bag of tricks regarding 
performance optimization (parallel arrays, hoisting allocations, etc) 
but systems compilers and techniques have also made solid progress. When 
it comes to getting "all" performance, the C model is where it's at.
