Hi,
I spent some time investigating mina performance. I've written two simple
multiplexing servers that collect 16 bytes from one connection and send it to
all other. One was using mina and another was using NIO directly. Comparison
program collects avarage lag in message delivery depending
Timur,
FYI, the attached parts have been removed by the mailer. Could you just post
them somwhere so we can read them ? The best solution would be to create a
JIRA issue, and to attach those files into it.
This is an interesting test you have done.
Thanks a lot !

We really really really need the documentation.
If you want to, make an HTML or Word document and I'll sent it to the Wiki.
Please don't get unmotivated because of technical concerns.
Even in notepad if you will!! But please write it!! =o)
Thanks!

I observed my mina server memory keeps increasing if there is incoming
packets, is it normal? My codec extends AbstractMessageDecoder and one
session on decoder instance. Thanks.
Hey Emmanuel,
I'm not sure I understand your point or if there is a problem. :) I would say
that it is fine and even expected to find that most of your CPU time is spent
in MINA (or I/O work) if your application is super fast (e.g. does not do much)
and all you do is send and receive data to
Hi, Gaston,
I forgot to tell that even if I use a faster server than the one where I ran
the tests (the tests were conducted on a dual core intel based iMac), I get
almost the very same resulst : no more than 2000 req/s (I also tested it on
a 8 dual core CPU server).
It looks like MINA itself

Hi Emmanuel,
Hi Csaba,
I'm a little bit puzzled but some of the results I get. First of all,
we are
using MINA-1.0.1, with different JVM (JRockit, IBM, Sun) on different
platforms (Linux, Mac OSx).
The published results are on Linux? What kernel are you

Greg,
I have done some more test, on the 'big server' ( 8 CPUs), changing the
SocketAcceptor initialization with something like what you suggested :

Emmanuel,
Awesome! That seems to have helped quite a bit.
Have you thought about using a profiler during the load test? I think MINA
has a YourKit Open Source license. Are we allowed to use that? It would be
good to find out exactly where the hot spots are and figure out whether

Just FYI, I'm working on implementing this in the new datagram transport.
That is correct, this is a relevant fix for improved performance on most
server machines, especially with multi-core quickly becoming ubiquitous. It
wouldn't be hard to change the default constructor. Perhaps you could open a
JIRA issue to request this, or submit a small patch, as MINA developers
I'm almost done with a first stab at a new datagram transport. It's about
1500 LoC. Should I just open a JIRA and attach it as I've done with patches
before, or is there a different process for something of this size? Maybe a
sandbox or something?
Let me know the best way to get started.
