Doc: do you have a jabsco pump directly to each bag (ie 3 seperate pumps feeding 3 bags bags). If so that sounds about right.

I'm going to leave my single jabsco and 3 bags and 'T' off my through-hull and add a tsunami 1200 with 1" line directly to my new 1100lb bag.

My single jabsco and sprinkler valves with springs removed is filling 2000lbs+ total right around 20 min mark.
