Hi,

As new users of Grizzly and having had no experience of previous
releases, I thought I'd share our initial impressions and
recommendations for 2.0. I don't know how much they make sense because
our experience is pretty restricted to using Grizzly as a pure IO
framework, and we don't have much interest in the Web related related
functionality (e.g. HTTP / Comet) at the moment.

So here goes: our first impression is that it's very easy to get lost in
the APIs and not know where to start (this may be a direct result of the
documentation being currently aligned on 1.9.x releases?). There seem to
be some key classes buried down in sub-packages and also overlapping
functionality (e.g. codecs vs filters). Another thing that bugs me is
that everything is public which adds to the confusion. Therefore I think
that some time should be spent on the following:

    * Update/finish Javadoc and update documentation on website.

    * Make an effort to hide as much implementation detail as possible:
      only expose classes / methods / fields which are intended for
      public consumption. Make classes/methods final where possible and
      document things that are intended for extension. All basic Joshua
      Bloch stuff really. :-)

    * All aspects of performance and scalability are absolutely critical
      for us, but we are not yet at a point where we can provide useful
      feedback (our Grizzly based prototype is not complete yet). Our
      initial impressions are good though :-)


Regarding Github vs Kenai and (and SVN vs other VCS). Being Java.net
based ourselves we understand the pain you are experiencing! :-( Before
migrating away I would consider the following:

    * Where do you plan to put the website content, mailing lists, WIKI,
      and bug tracking? I don't think Github provides support for any of
      these from a first glance, although I could be completely wrong.

    * User migration / authentication: I wouldn't be surprised if
      Project Kenai provides a migration path for users from java.net.
      It's probably worth checking.

    * SVN vs Git vs Hg, etc: personally I would stick with SVN as it's
      fine for most needs, is easy to use, and has very good IDE support
      in Netbeans, Eclipse, and IntelliJ. Our experience of using SVN
      and Hg internally is that there is no noticeable performance
      difference (probably the same applies for Git but I'm just
      guessing) - the reason SVN is slow for us is more to do with
      Java.net than anything else. So I suggest changing provider first
      before changing VCS.

Matt
