Hi, thanks for responding so quickly,

I'm looking at the <QTime> value in the Solr response.

This is basically a test that I'm doing and it's not in production yet, so I
did a one time index and I haven't committed any new documents.
- JVM heap size is 12 GB
- I am autowarming
- Index is optimized
- useCompoundFile is false

>You said you've "done most of the optimizations", can you be specific?

- I have a minimum # of stored fields, 5 out of 25.
- My index is optimized
- HashDocSet is set to around 75000
- I've setup autowarming queries
- Haven't warmed sort fields because I'm not doing any sorting
- Not using any solid state drives
- Using filters instead of queries for filtering.
