View Slide

W’en wreed vele
biegeleerd

View Slide

Mo ’t ed
tied
gekost

View Slide

De eerste
pogingen

View Slide

Eerste pogingen
✓Dikke machinen derachter zetten
✓Vele heheuhen en zwoare CPU’s
✓Loadbalancing ip de webservers
✓Master/master op de MySQL’s
✓Hoge memory limit
✓APC byte code caching

View Slide

Ip zoek no
Magento
kennisse

View Slide

Eerste Magento
kennisse
✓Caching activeren in ’t admin panel
✓Flat catalogs
✓De Magento compiler
✓JS & CSS minification

View Slide

Magento compiler is
dikke zever en een
hoop miserie!

View Slide

Gebruukt een echte
byte code cache in
de plekke

View Slide

’t Gienk ol een klein bitje
rapper
Mo nie voe te roepen

View Slide

Eerste concluuzjes

View Slide

Eerste
concluuzjes
✓Gelik verwacht vele RAM en CPU
verbruuk
✓Verdacht vele I/O
✓Meha vele belastienge ip de MySQL

View Slide

W’en leren cachen
