load imbalance is only a performance issue.

Load balancing affects binary reproducibility (meaning the exact same value)
but not accuracy (those it can differ but only within the same accuracy).
Binary reproducibility should only be important for testing purposes, thus
you should use load balancing to improve the performance if you have
a significant imbalance.
