Are you requesting results by relevance or are you sorting by a field?
How many results are you requesting?
Are you using real user queries (with repetition) or a flat
distrubution of queries?

Greetings,
I'm running a solr instance with 100 million documents in it. The
index is
18 GB.
The strange behavior I'm seeing is CPU utilization gets maxed out. I'm
running on an 8 core machine with 32 GB or ram. Every concurrent
query I run
on it uses up one of the cores. So, if I am running 1 concurrent
query I'm
using up the cpu of one of the cores. If I have 8 concurrent queries
I'm
using up all of the cores.
Is this normal to have such a high CPU utilization. If not, what am
I doing
wrong here. The only thing I have modified is the schema.xml file to
correspond to the documents I want to store. Everything else is just
using
the default values for all the config files.
Thanks.
