The ES "memory" or "ram" store (Lucene RAMDirectory) puts enormous pressure on JVM garbage collection.
You can not expect that standard JVM with CMS GC can give the best performance. More info in this great article by Mike McCandless http://blog.mikemccandless.com/2012/07/lucene-index-in-ram-with-azuls-zing-jvm.html Maybe Java 8 with G1 GC is giving slightly better numbers. But do not expect too much.
