Chris, There is an amplot utility that I used to run a lot, it would show me what I was constrained on, often holding space, which if you are running a bunch of large dumps to start off with could constrain dumping later on.

Here are some stats from amstatus for this config. It looks like I could drop about half of the dumpers and still be fine. Any idea what causes the dumpers over the first five to be utilized less? dumper0 busy : 5:13:42 ( 97.98%) dumper1 busy : 1:12:09 ( 22.54%) dumper2 busy : 0:40:30 ( 12.65%) dumper3 busy : 0:33:44 ( 10.54%) dumper4 busy : 0:03:47 ( 1.19%) dumper5 busy : 0:37:32 ( 11.73%) dumper6 busy : 0:02:00 ( 0.62%) dumper7 busy : 0:00:57 ( 0.30%) dumper8 busy : 0:05:54 ( 1.85%) dumper9 busy : 0:04:38 ( 1.45%) dumper10 busy : 0:00:16 ( 0.08%) dumper11 busy : 0:01:39 ( 0.52%) dumper12 busy : 0:00:01 ( 0.01%) 0 dumpers busy : 0:02:43 ( 0.85%) 0: 0:02:43 (100.00%) 1 dumper busy : 3:39:13 ( 68.47%) 0: 3:39:13 (100.00%) 2 dumpers busy : 0:23:10 ( 7.24%) 0: 0:23:10 (100.00%) 3 dumpers busy : 1:07:57 ( 21.22%) 0: 1:07:57 (100.00%) 4 dumpers busy : 0:02:09 ( 0.67%) 0: 0:02:09 ( 99.99%) 5 dumpers busy : 0:01:07 ( 0.35%) 0: 0:01:07 ( 99.98%) 6 dumpers busy : 0:00:03 ( 0.02%) 0: 0:00:03 ( 99.59%) 7 dumpers busy : 0:00:43 ( 0.22%) 0: 0:00:24 ( 56.35%) 5: 0:00:09 ( 22.36%) 4: 0:00:08 ( 18.89%) 1: 0:00:01 ( 2.37%) 8 dumpers busy : 0:00:20 ( 0.10%) 0: 0:00:19 ( 96.50%) 9 dumpers busy : 0:01:51 ( 0.58%) 0: 0:01:51 ( 99.98%) 10 dumpers busy : 0:00:41 ( 0.22%) 0: 0:00:37 ( 89.71%) 5: 0:00:02 ( 7.13%) 4: 0:00:01 ( 3.09%) 11 dumpers busy : 0:00:07 ( 0.04%) 5: 0:00:07 ( 99.54%) 12 dumpers busy : 0:00:00 ( 0.00%) 13 dumpers busy : 0:00:00 ( 0.00%) I am going to give things another week or so and then try breaking up some of the very large DLEs in the config.
