15. Performance Basics - Piecing it together
Client
❏ CPU
❏ How much can the machine handle?
❏ Processing time & effort
❏Browser limitations
❏ Request volume limits
❏ To same domain
❏ In total
❏Site code

16. Performance Basics - Piecing it together
❏ Bandwidth
❏ “Size” of the pipe
❏ How much can the internet connection handle at
once?
❏ Distance travelled
❏ The internet is literally a bunch of wires. While
small, location matters
❏ Connection Speed
❏ How quickly can our requests and responses travel?
Connection/“Pipe”

21. Tag Factor and their impact
❏ Additional requests
❏ Content loading (if sync)
❏ Processing necessary (CPU usage, request limits, etc.)
❏ Layout and display (depending upon function of tag)
❏ Takes bandwidth

❏ How do users access your site?
❏ Where are your users?

24. Optimizations and what to look for
❏ Tag considerations
❏ How does tag load?
❏ What is tag/platform doing?
❏ Piggybacking (“Daisy-chaining”)
