Exam AD0-E104 topic 1 question 8 discussion

A client's marketing pages are generally slow to load which is causing a significant drop in sales. All other AEM pages load within expected performance guidelines regardless of whether the visitor is being served the desktop or mobile experiences.
The marketing pages typically get slower when multiple external campaigns such as Facebook or AdWords drive traffic to those pages. The page performance tends to dip during high traffic periods Internal campaign clicks such as those from hero images use similar campaign codes as external campaign traffic.
What should the Architect do to resolve this issue?
