Hi Nuno,
I'll try it tomorrow, sounds very simple, but we'll see ;)
ok.
Are there advantages concerning the memory usage or other
performance issues?
maybe it will use less memory because Spread uses a different
approach: the java side of the code is a very simple client that just
connects to the daemon to send/receive messages. The high tech is all
in the daemon, not in the client that is used by a java spread
application (in this case, the controller). So, off course the
controller process will spend less memory, part of the code is being
executed in another process.
I think that you will not have a great performance because of their
Java API. Something is not good about this API and makes it run very
slow. We after built another java API for Spread and runs quite
faster. See http://jgcs.sf.net. This is a generic API also with
several implementations and one of the bindings is for Spread. To
implement that, we used JNI.

Hi,
the reasons for this implementation were simple: I needed it, so I
implemented it. I had the code, so I just decided to contribute it
to the forge :)
just install the spread daemon on the machines were you will run
the controller, get hedera from CVS, compile it and add the jars
to Sequoia. use the hedera_spread.properties file instead of the
hedera_jgroups.properties or hedera_appia.properties.
Cheers,

Hi @all,
today I (I think the first time) read something about an Spread
implementation of Hedera.
What are the reasons for this implementation, are there benefits
compared to using appia?
How can I easily test a bit with spread? Is it possible to change
to spread, as easy as it was to appia?
Best Regards,
Malte
