Of course is Java 8 worth the effort. Some highlights:
- no more permgen OOMs - improved concurrency implementations: http://docs.oracle.com/javase/8/docs/technotes/guides/concurrency/changes8.html - faster hash maps (20%) - lambda expressions are faster than inner classes Some concurrency classes like LongAdder are already included in ES. Java 8 JVM brings also G1 GC to its full extension. G1 GC is not faster than CMS GC, but it scales much better over multicore and reduces stop-the-world pauses to milliseconds. To exploit the full advantage of Java 8, ES would need a large overhaul by rewriting inner classes to lambda style, streams, fork/join pool etc. As long as Lucene does not switch to Java 8, the benefit is only partial.
