The JVM uses reserved memory, buffers, and stacks beside the heap, most can not be controlled by user settings. To reduce memory as much as possible for a Java process, do not use mlockall tricks, use 32bit JVM and reduce maximum allowed stack size with -Xss (this will affect performance of course)
You will also need many tweaks of Elasticsearch default settings to behave under shrinked memory, for index loading, field caches, etc. Jörg -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
