In addition to the basic requirements that a Solr server have 2 CPU cores and 8 GB RAM, there are some other practices that enhance the performance of crawls and querying.
The number of drive spindles is a key contributor to better search performance. The best practice is to provision three spindles as follows:
- C: - operating system
- D: - Solr install
- E: - Solr index
The Solr install is where the installer placed the core components, including the crawl database. During the install, the wizard prompts for the Solr index location.
For optimal performance, the disks should be high-performance drives.
