Hello,
I'm about to move from development to launch on a project that uses solr to index around 800,000 nodes. At present it is on a dedicated server with 4gb ram, along with about 15 other websites I host. It is clear that under load I am experiencing slow downs in mySQL from a lack of memory, and from what I've read it appears the RAM allocated to Solr is a major factor in how fast and responsive your solr searches are.
What I'd like to know is
-
Should I be aiming to upgrade this server with more memory, or to launch a new box that is dedicated to mysql/solr/both?
-
In either case, what level of memory is likely to be sufficient?
Thanks!
