Lots of little memory allocations/deallocations. The major JVMs have extremely efficient memory subsystems, and garbage collection can be more efficient than requiring explicit freeing (plus it can shift memory addresses and such if it really wants to). Efficient access through deep hierarchies of method calls. The JVM is very good at eliding anything that is not necessary, usually better in my experience than most C++ compilers (including gcc and icc). In part this is because it can do dynamic analysis at runtime (i.e. it can overoptimize and only deoptimize if it detects a problem). Encapsulation of functionality into small short-lived objects. read less
