It is partly true that taking a long time to fill tanks could lead to
a problem.

The usual problem is inconsistent results.  This is most easily
overcome by being very consistent in your technique and selecting
developers that take a reasonably long time (e.g., more than 5
minutes).  Uneven development is more likely caused by incorrect
agitation.

The Jobo system (also mentioned) does a fine job, but there are
simpler systems (i.e., involving less equipment).
