Run a test by writing testSize numbers into a memory of memorySize, then reads the numbers back out again.
Run a test by writing testSize numbers into a memory of memorySize, then reads the numbers back out again. With a fixed testSize the run times should be the same despite the size of the memory
number of elements in memory
number of values to write and read from memory
This regression demonstrates that a bad initial setting has been fixed the default rollback buffer of 10 meant that large memories caused considerable slowing as buffers were copied.
