Roamio Pro - sluggish and slow transfers

I recently upgraded to a Pro for my primary TiVo, while copying recordings from my 4 tuner Roamio to the Pro, the pro got slow, during the transfers (from just a another single Roamio) changing channels was slow, basicly the entire UI was slow while navigating menus. On top of that, during the transfers, two of my Minis wouldn't connect to the Pro, C53 error I think not sure exactly buts it's the error indicating it couldn't find the pro.



The Pro is connected to gb Ethernet , two minis bt Moca, the Pro is the Moca gateway. I didn't try my third mini which connected by Ethernet.



I managed to get a little better menu response on the Pro by tuning its unused tuners to blank channels which seemed to help the pro slightly but only by a little. But it concerns me that a single 100mb basic Roamio MRV transfer totally bogged down the Pro.



Anyone else seen anything like this? I'm becoming concerned that the Pro isn't as good as I thought it should be. Fyi, I have a full managed Gb Ethernet switch that all my TiVos are connected to and I'm not seeing errors such as collisions, transmits or media errors at the connected ports is its not the network.



I'm reconsidering using the Pro as my Moca to Ethernet gateway, if one transfer from another TiVo, almost kills my Pro what's the point if having it? My former two 4 tuner Roamios never had a problem with recording transfers while servicing the Minis connected to them.



I have a few things I'm going to try network wise to see if I can get better performance but so far I'm becoming concerned that the Plus/Pro Roamios aren't as good as TiVo claims they are!
