> [@autobalance](#): > > 130 in total including tags not being actively shown e.g., in a carousel component Fairly certain it doesn't matter if they're being displayed or not. If they are on the active view they're being processed. Not that 130 is a massive number of tags to be active. I haven't done any testing to verify this, but I believe that this is true even of things hidden behind a tab. Willing to be corrected on that though. > [@autobalance](#): > > The embedded views in question are often 1-4 embedded views deep before reaching just a component. This is definitely not helping performance, at least not when the view is loading/refreshing. I know that @YF129701 says they have nesting up to 3 levels deep, but this has been a known performance hit for some time. Recommendation is to avoid nesting over 1 level. A few here and there will not hurt, but get many of them on a view and you'll take a hit. > [@\[Feedback\] Perspective view load-ahead optimization](https://forum.inductiveautomation.com/t/feedback-perspective-view-load-ahead-optimization/45309): > > An important new optimization for Perspective view loading has just been merged and will be available in the 8.1.5 nightly starting tomorrow, 4/7. This optimization nearly eliminates the performance penalty of composing pages/views using embedded sub-views by loading them ahead of time with their parent, reducing or eliminating browser layout thrash and providing a more pleasant navigation experience. The load-ahead logic is compatible with Embedded View, Flex Repeater, and Tab Container compon… Are there any other applications running on the Gateway? Otherwise, here is a "generalized list" of things to look for when looking at performance in perspective: > [@Building for Performance](https://forum.inductiveautomation.com/t/building-for-performance/71082/3): > > In this example, #3 is the most performant, though it could be argued that the performance gain in this instance would be negligible. Anytime you add an additional processing step you add latency. In general for the best performance I follow these guidelines: If you can achieve what you want with a binding, use a binding. Always use the binding type that is the most direct. (e.g. if all you need is a binding to a property use a property binding, not an expression binding.)
