| # System Requirements |
| |
| Apache Solr runs of Java 7 or greater, Java 8 is verified to be |
| compatible and may bring some performance improvements. When using |
| Oracle Java 7 or OpenJDK 7, be sure to not use the GA build 147 or |
| update versions u40, u45 and u51! We recommend using u55 or later. |
| |
| It is also recommended to always use the latest update version of your |
| Java VM, because bugs may affect Solr. An overview of known JVM bugs |
| can be found on http://wiki.apache.org/lucene-java/JavaBugs |
| |
| With all Java versions it is strongly recommended to not use experimental |
| `-XX` JVM options. |
| |
| CPU, disk and memory requirements are based on the many choices made in |
| implementing Solr (document size, number of documents, and number of |
| hits retrieved to name a few). The benchmarks page has some information |
| related to performance on particular platforms. |
