I'm trying to improve query performance. It takes an average of about 3
seconds for simple queries which don't even touch a nested document, and
it's sometimes longer.
Even without the sort it takes seconds. Here are the details of the cluster:
1.4TB index size.
210m documents that aren't nested (About 10kb each)
500m documents in total. (nested documents are small: 2-5 fields).
About 128 segments per node.
3 nodes, m2.4xlarge (-Xmx set to 40g, machine memory is 60g)
Index is on amazon EBS volumes.
Replication 0 (have tried replication 2 with only little improvement)
I don't see any noticeable spikes in CPU/memory etc. Any ideas how this
could be improved?
