2.5GB RAM, pretty modern virtual servers

Let's say a few queries per second max... < 4
And in general the challenge is to get latency on any given query down
to something very low - we don't have to worry about a huge amount of
load at the moment.
> - document cache and query cache settings
<queryResultCache
class="solr.LRUCache"
size="512"
initialSize="512"
autowarmCount="256"/>
<documentCache
class="solr.LRUCache"
size="512"
initialSize="512"
autowarmCount="0"/>
> - your current response times
This depends on the query. For queries that involve a total record
count of < 1 million, we often see < 10ms response times, up to
4-500ms in the worst case. When we do a page one, sorted query on our
full record set of 2 million+ records, response times can get up into
2+ seconds.
> - any pain points, any slow query patterns
Something that can't be emphasized enough is that we can't predict
what records people will want. Almost every query is aimed at a
different set of records.
