What is the difference between early build and lazy build in vFlow?
Early load will load the complete configuration of any vFlow app at the time of first load. That means your application will be in slow to load but afterwards it will execute faster.
Lazy load will only load the required configuration of the current page. This helps in faster first load but subsequent loads to any page would be slower than early load.
Remember, there is no one stop solution and one should choose between the two according to the project needs.
