That initial delay is pretty bad, it should be mitigated by vulcanization, and obscured by un-inlining the network settings. It is *much* less noticeable on a device like Pixel, but I will do some testing against a lower end machine once Vulcanization has landed.

Vulcanization mostly helps with the page's loading time. Once the page has loaded, it has minimal effect AFAIU. So I don't think it will positively affect the time it takes to load WiFI networks.

stevenjb@: maybe we could issue a request to load the wifi network in the background after the page is idle? see: requestIdleCallback() this is also how we pre-render the advanced section

Yep, that's an option. It might help with overall performance also (we could delay some other requests until an idle frame). I definitely plan to look into this for 58.

This will be resolved with un-inlining the networking UI (which will also defer a bunch of blocking operations) |
