Quick #sustainableIT #webperformance tip:

Remove Google Universal Analytics (UA) from your website. I spotted two UA tags on a client’s site and ran a comparison using WebPageTest on a low-tier device: blocking two UA tags results in 13% less Total Blocking Time (here in red).

UA no longer processes data and:
👎 takes up bandwidth on initial load (50 KB of JavaScript)
👎 busies the processor (around 150ms CPU time on a low-tier device)
👎 can slow down your iteraction responsiveness (INP)
