Chapter 4. BUILDING THE VPS 18

Slide 19

Slide 19 text

$10 = 1 CPU, 1GB, 30GB • Cheaper plan is just too small. • 1GB is enough for moderate use but will not allow Solr and memory use will be ~700-800MB active • 2GB would raise MySQL cache, allow for Solr (~200MB) and leave some room for more performance. • 4GB is expensive -> Dedicated 19
