Android always has a performance penalty because software runs in a JVM....

  There is no JVM in Android. Android uses the ART runtime that compiles apps to native ARM, x86, MIPS, etc code.

  We're talking about the performance penalty compared to normal Android. Baseline performance penalties (compared to ...?) are present in both environments. Besides, the JVM is a very good optimizer, and a good choice for certain types of high-performance tasks, especially since it can continually re-optimize the program as needed. It beats C in one of the anecdata on the Benchmarks Game, and is competitive in a few others: http://benchmarksgame.alioth.debian.org/u64q/java.html http://benchmarksgame.alioth.debian.org/u64q/java.html

    What "beats C" is a "custom counted hash set".
