Pages take a long time to load with href attribute

Hello everyone.
I’m having trouble with the links inside my Ionic 4 applications, more specifically with page load time.
I created some test apps with blank templates, sidemenu and tabs and they all have the same problem: when I click on an item with the href attribute, it takes a long time to load the requested page, even if it has only the title in the header, with no more content.
By clicking the tab icons at the bottom, the pages (screens) load quickly, even if they were created manually. The problem is only in pages loaded via href.
I do not know what to do to solve this.

why don’t you use ionic/angular navigation ?
