NewRelic is the performance monitoring platform that is included in our WPEngine hosting subscription.
Each week we receive a performance report for the livechhs site.
The weekly appdex is a measure of how well the site did with regards to response time, throughput, and errors. If rating is Bad it warrants immediate exploration. If the rating is Good it’s worth investigating further. If the rating is Excellent, then it’s smiles all around.
WPEngine support has been historically very responsive and helpful and pinpointing the cause of degraded performance. See WPEngine - Hosting for more information.
