Hi, Wondering if anyone can offer any advise on this as I have looked around and cant really seem to find an answer on this. Since updating to Java 7 64 bit from Java7 32 bit and increasing the MAX\_HEAP\_SIZE I am seeing slower query performance when trying to query data via the Plugin GUI's such as Elasticsearch HQ. On the stats page for the GUI, the only part which was RED is the index refresh. This is now currently Yellow after lowering the MAX\_HEAP\_SIZE to 4gb from originally 50% of the total which was 32. (Set to 16GB originally when updating to Java 7 64) Any ideas on why after updating to Java7 64 and upping the HEAP that this would affect performance so dramatically as it was faster when using java 32 with a lower heap. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
