I am not surprised about the Java performance. URL related: http://java-is-the-new-c.blogspot.com/2014/12/a-persistent-keyvalue-server-in-40.html http://java-i

  The ample usage of ";-)" is a pretty reliable indicator of the author being german. Not sure what that means.

  I really hope this gets into Java9 http://objectlayout.org/ http://objectlayout.org/ Gives the same benefits as C structs while still behaving like Java objects. i.e. has the structs memory semantics while having java function/method semantics associated with the memory. Better explained in this presentation http://medianetwork.oracle.com/video/player/3730888956001 http://medianetwork.oracle.com/video/player/3730888956001 (there are other sources as well).

    Thats a good one, Gil Tene is really a good speaker. For anyone who (like me) thinks: "structs are just classes without methods, why are they faster?". The answer is that this is about arrays, which are currently slow in Java because they are: - mutable: elements can be changed, nulled etc. - polymorphic: they can contain T or subtype-of-T This makes fast streaming of objects impossible, because you need to deref the object. If this changes, object addresses can be calculated like in C, which makes things fast - flat memory is fast, prefetchers work their magic.
