I marked corresponding computers with a number in parentheses. (0) is my own computer. In particular, 5 of my pending work units are waiting for the same computer (7), which has an average turnaround time of 10.53 days. I haven't found these coincidences with other projects.

Locality scheduling can frequently pair your host with one or more other hosts that take 10-14 days to return results. Folks become anxious when their results are pending for a long time and patience is not everyone's virtue.
