Safari is parsing all included JS files and causing page loadtime to shoot up

Hi,

We are using ember js for for web application. In Safari, the page is taking around 18 secs to load.

We broken down the JS into small parts & successfully loaded them. But the Safari browser still takes considerable time to load the main page.

Any thoughts on - how to address this ?

We have other methodologies but trying to avoid more work while navigating to other links in app.

Note: Ember fastboot may be an option, but I donot think that it might work for our scenario

is it all because javascript?

I had a issue like this. But it’s because de load model in application route. So I load a empty page and after it’s render starts to load the resources. Could u have same experience by access slack. Slack renders a big placeholder and after that it starts to load content.
