It's a little difficult to be sure. We have a HT box and the
CPU % we get back is misleading. I think it's safe to say we
may spike up to 100% but we don't necessarily stay pegged there.

We can't do it b/c during the unresponsive time we can't access
the admin site (/solr/admin) at all. I don't know how to do a
thread dump via the command line....

Forgive me when I say I'm not totally clear on what this
question means. The index is constantly getting hit with
a myriad or queries, if that's what you meant....
Thanks,
