 +====== Performance ======
 +=====Preload Your database into RAM=====
 +Find your database's oid and make a note of it:
 +<code>
 +psql -U evergreen -h localhost -d postgres -c "select oid from pg_database where datname = 'evergreen'"
 +</code>
 +
 +Then, as the root or postgres user, run the following commands
 +<code>
 +cd /var/lib/postgresql/${pgversion}/main/base/${oid}
 +cat * > /dev/null
 +</code>
 +
 +Replace ${pgversion} with your PostgreSQL version number, ex. 9.5.  Replace ${oid} with the number returned by the database query.

 +order by 4 desc
 +
 +</code>
 +
 +You will need to edit that query to look for reports owned by a particular actor.usr.id. Replace "!!!REPLACE ME WITH OWNER ID!!!" with the ID number. This is useful when you have centralized report templates for everyone to use. It also takes into account cloned reports from the same source template!

 Similar to the spell above, this can be used to clear all cached catalog search results and facets from memcached. This ordinarily isn't needed for production use, but can be useful when testing tweaks to search code or settings. Similar to the spell above, this can be used to clear all cached catalog search results and facets from memcached.
