Cache a optimilizácia

• Obsah špecifický pre konkrétneho zákazníka
  • /cart
  • /checkout
  • /my-account
  • /* (bloky s informáciami)
     
• Vylúčiť  tieto podstránky z cacheovania
• Pomôže AJAX
  • Alternatíva je "sledovať " správanie:
    Je návštevník e-shopu už zákazníkom? 
• Angular/React?

Chcete naozaj rýchlosť?

• WordPress Object Cache
  • Redis/Memcached
  • Aplikuje sa aj na Transients API

  • RAM > veľkosť databázy
  • Čím viac CPU tým lepšie :)
