When you run multiple threads on the same machine with the same memory
limit, you get much more memory use. Garbage collector in JVM is 'stop the
world' by default. This means that with increased memory churning you
spend more time in all the threads waiting for the garbage collector to
complete (which has low priority, by the way).

You need also four times more memory and/or ParallelGC enable to benefit
 from multiple threads.
