Performance
Slow is a decision, not a condition
02 / 05
The usual causes
Five things, nearly every time
01
Images straight off the camera
A 6MB photo displayed at 400 pixels wide is 6MB of waste.
02
Third-party scripts
Every tag, chat widget and pixel is a promise someone else can break.
03
No caching
Rebuilding the same page for every visitor is work nobody asked for.
04
Render-blocking code
The browser waits for files it does not need yet.
05
Cheap shared hosting
You are sharing a server with whoever is having their busiest day.
03 / 05
What we do about it
The fix, in order
01
Measure with field data from real devices
02
Process images at upload, not by hand
03
Audit every third-party script for what it returns
04
Cache and serve from the edge
05
Monitor so it does not slide back
04 / 05
Every third-party script is a promise someone else gets to break.
