Green threads, the threads provided by the JVM, run at the user level, meaning that the JVM creates and schedules the threads itself. Therefore, the operating system kernel doesn't create or schedule them. Instead, the underlying OS sees the JVM only as one thread. Green threads prove inefficient for a number of reasons. Foremost, green threads cannot take advantage of a multiprocessor system(...) Thus, the JVM threads are bound to run within that single JVM thread that runs inside a single processor.
