Performance of Web View inside of iOS shell

We are working on an internal enterprise iOS application which we need to host a pretty complex web page inside. We have been reading regarding the WKWebView and how it performs inside of iOS shell, but there is no real data on what are the limitation of the WKWebView in terms of memory for the hosted Web Page.

Let's say we could measure our iOS app before the WKWebView is launched and after it is launched. We see that the memory consumption of the web page loaded into WKWebView is X mb. How would we know that iOS would allow an app with such webpage loaded into WKWebView and won't terminate the app which the web page is loaded.

Is there any documentation regarding on what is the maximum allowed memory for the web page which is hosted inside of WKWebView?

And another question, for the Enterprise Developer Program are there any ways to increase the limit of the memory a specific iOS app is allowed to consume before it is terminated from iOS device due to low memory warning from iOS?
