Hello @BRNAIDU85 ,
I hope you doing great.
Please go through below information which is mentioned in outsystems performance suggestion warning document.
Message'<OnInitialize action>' contains accesses to the local storage or server, which delays the <screen | block >'s render. To avoid performance issues, use Aggregates or Data Actions instead.CauseThe rendering of the screen/block only starts after the OnInitialize action finishes. If you access the local storage or execute requests to the server during this stage, you may delay the rendering of the screen/block and make the app look unresponsive.RecommendationMove all logic that accesses local storage or server into Screen Aggregates or Data Actions. This way the rendering starts sooner and the fetching of the data or running other server operations runs concurrently, while the screen/block is rendering. For more information, see the Screen and Block Lifecycle Events documentation.

Ajit kurane.
