Performance issue.

[Gmail Account]

Sorry.. I put the wrong subject on my message. I also wanted to mention that 
my cpu jumps to to almost 100% each query.

I'm having slow performance with my solr index. I'm not sure what to do. I 
need some suggestions on what to try. I have updated all my records in the 
last couple of days. I'm not sure how much it degraded because of that, 
but it now takes about 3 seconds per search. My cache statistics don't 
look so good either.

Also... I'm not sure I was supposed to do a couple of things.
   - I did an optimize index through Luke with compound format and noticed 
in the solrconfig file that useCompoundFile is set to false.
   - I changed one of the fields in the schema from text_ws to string
   - I added a field (type="text" indexed="false" stored="true")

My schema and solrconfig are the same as the example except I have a few 
more fields. My pc is winXP and has 2gig of ram. Below are some stats from 
the solr admin stat page.

Thanks!
