ANALYSIS: Number of HTTP requests
ANALYSIS: Page Weight
ANALYSIS: DOM Complexity
Number of visits per year for the page

INFOS

The lower the better. Calculated using DOM complexity / Page size and number of HTTP Requests
Less HTTP Request = less network usage = less server usage = better performance
Page weight causes network usage and can cause low local performances
It is recommended that the pages contain less than about 1 500 DOM elements for better accessibility.
Each visit generates network consumption, server consumption and device obsolescence

Mobile / Tablet in %
Laptop / Desktop in %

INFOS

Mobile phone or tablet have less memory and CPU capacity. DOM and Http Request will impact more these devices

BEST PRACTICES

  Is there a old media deletion policy?
  Is there a database lifecycle policy?
  Is there a logs deletion policy?
  log retention time in years

INFOS

Consider deleting old media when not used
Databases are rarely purged from old data
Logs must be deleted when not used
Depending of the activity, when can consider deleting logs could be done once a year
