solr

I'm relatively new to solr. I have a production site running on a VPS, but now I'm having serious load issues. I don't know where to start in order to get the load down...

VPS specs (linode.com 512)

512 MB RAM
4 CPU (1x priority)

Looks like my solr server (tomcat) is using a lot of CPU power

You can find my solrconfig.xml on http://pastebin.com/qdfi8Med and my schema.xml on http://pastebin.com/rRusDP8b

I've tried to increaese the cache size, but this didn't do anything on the load. You can see the stats page below.

EDIT - Because the screenshot was unclear, I took smaller screenshots if what (I think) is important.

Thanks for the help!
