The load time negatively affects the engagement rate
Speaking from a personal experience, if the load times on IH were faster, I'd be more active. Sometimes a page can take up to 8 seconds to load. So I usually just rely on the notifications I get on my email and avoid opening the site. Is there an Android app I can use?
Have you verified that it is the IH url that is hanging? 8 seconds seems strange. Can you share your findings? I have no problem loading all my pages here on my phone without latency.
