Thingworx 9.2 Collection widget performance issues

I have been using the collection since it's initial release in I believe 8.2. Prior to that I used the repeater widget.

There are ALOT of possibilities you can do with the collection widget but the performance has always been a big issue and in 9.2 it seems like it may have gotten worse.

Full disclosure, I realize maybe I am not using it as intended, but I can't find much on best practices and such to tell me otherwise.

So, my current situation is as follows:

• I have a mashup that uses a collection widget to create an input screen.
• The collection widget is populated by a service that creates an infotable that will return at most 31 rows. Each row represents a day in a month. I loop through each day to return the results for that day if it exists, if not the values are empty.
  
  
• When I execute the service in composer the results come back in < 2 seconds
• I originally had the load behavior on the collection widget as load/unload. Which still wasn't exactly fast but I noticed all rows weren't saving since everything wasn't within view. So, it unloaded, makes sense. So I switched it to Load All and now, it takes >30 seconds to load which makes the page unusable.
• There is one thing that runs on each individual row mashup,
  • insert/update service
    • triggered by a session parameter changing (main mashup where infotable is returned sets this value. There is a save button on the main mashup that triggers an expression that spits out a random value, stores in the above mentioned session parameter)
  • There are numeric entries that are populated by the mashup parameters from the infotable.

Does anyone have any thoughts about what I could do to fix this?
