It looks like file locking was the bottleneck - CPU usage is up to ~98% (from
the previous peak of ~50%). I'm running the trunk code from Dec 2 with the
faceting improvement (SOLR-475) turned off. Thanks for all the help!

You need to apply this source code patch to Solr:
https://issues.apache.org/jira/browse/
I'd like to integrate this improvement into my deployment. Is it just a
matter of getting the latest Lucene jars (Lucene nightly build)?

Right, for single-threaded requests. FastLRUCache has faster gets and

I'll try changing my other caches to LRUCache and observe performance.
Interestingly, the FastLRUCache has given me a ~10% increase in performance,
much lower than I've read on the SOLR-667 thread.
Would compressing some of my stored fields significantly improve
performance? Most of my stored fie

Where is the alt directory in the source tree (or what is the JIRA issue
number)? I'd like to apply this patch and re-run my tests.
Does changing the lockType in solrconfig.xml address this issue? (My
lockType is the default - single).

What are your other cache hit rates looking like?
Which caches are you using the FastLRUCache on?

Does the number of searcher affect CPU usage ?
Not totally sure about it but I think some versions of Tomcat were not
totally scalable over 4 CPUs (or 4 cores).

I ran a test without faceting. The response times / throughput were both
significantly higher, there
The latest alt directory patch uses It.

One quick question are you seeing any evictions from your
filterCache? If so, it isn't set large enough to handle the faceting
you're doing.
