An overview of known JVM bugs 24can be found on https://cwiki.apache.org/confluence/display/LUCENE/JavaBugs 25 26With all Java versions it is strongly recommended to not use experimental 27`-XX` JVM options. 28 29CPU, disk and memory requirements are based on the many choices made in 30implementing Lucene (document size, number of documents, and number of 31hits retrieved to name a few). The benchmarks page has some information 32related to performance on particular platforms. 33
