Hi,

I have a question about the deployment configuration in solr cloud.  When
we need to increase the number of shards in solr cloud, there are two
options:

1.  Run multiple solr instances per host, each with a different port and
hosting a single core for one shard.

2.  Run one solr instance per host, and have multiple cores(shards) in the
same solr instance.

Which would be better performance wise? For the first option I think JVM
size for each solr instance can be smaller, but deployment is more
complicated? Are there any differences for cpu utilization?

Thanks,
Wei
