Tips & trick to decrease startup loading time in perspective

Ignition Early Access

Old topic, but still relevant!!

Don’t use multi-level nested embedded views (EVs)!
e.g.

View
-> Embedded View
   ->Embedded View
      ->Embedded View

I did a comparison of load times in 8.1.18 between using EVs with no nested EVs, and EVs which contains EVs that have at least one level of nested EV, and the results are incredible.

1st part (1.3s) - EVs with no nested EVs
e.g.

View
-> Embedded View 1
-> Embedded View 2
-> Embedded View 3

2nd part (12.2s) - EVs with nested EVs that also have nested EVs - ignore the graphical crappiness… also it would actually be slightly longer than this as I’m missing one of the template Views
e.g.

View
-> Embedded View 1
   ->Embedded View
      ->Embedded View
-> Embedded View 2
   ->Embedded View
      ->Embedded View

I’m still curious why IA weren’t able to “flatten” the main Views on the gateway before sending to the clients :thinking:
The main hurdle when I briefly looked at it was the inconsistent way of referencing parent level components (Perspective relative references to parent component properties), making it far more difficult to replace bindings in embedded views with their flattened versions :confused: certainly not a roadblock though. I’m curious what the roadblock(s) was/were?
