BUILDING THE VPS
22
$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
