--minheap " size" Set the minimum heap size. The heap will not shrink below this value.
--maxheap " size" Set the maximum heap size. The heap will not grow above this value.
--gcpercent " percent" Set the target percentage of time that the code should spend in the garbage collector. The heap sizer will attempt to set the heap size to achieve this target consistent with the minimum and maximum heap sizes given by the arguments and also consistent with keeping paging under control.
--gcthreads " threads" Sets the number of threads used in the parallel garbage collector. Setting this to 1 forces the garbage collector to be single-threaded. The value 0, the default, is taken to be the number of processors (cores) available.
