Component	Java Heap	CPU	Disk
Solr	Small workloads, or evaluations: 16 GB Smaller production environments: 32 GB Larger production environments: 96 GB is sufficient for most clusters. Set this value using the Java Heap Size of Solr Server in Bytes Solr configuration property. See	Minimum: 4 Recommended: 16 for production workloads	No requirement. Solr uses HDFS for storage.

Note the following considerations for determining the optimal amount of heap memory:

Size of searchable material: The more searchable material you have, the more memory you need. All things being equal, 10 TB of searchable data requires more memory than 1 TB of searchable data.
Content indexed in the searchable material: Indexing all fields in a collection of logs, email messages, or Wikipedia entries requires more memory than indexing only the Date Created field.
The level of performance required: If the system must be stable and respond quickly, more memory may help. If slow responses are acceptable, you may be able to use less memory.
