Hi,
I just start using mina. I want using mine to build a server
which can support big connections(e.g. 10K).
After read the tutorials and the mina demo code, I change the echoServer to
test the performance , I want use the Thread Pool to handle the coming
connections.
so I add a ExecutorFiter to the FilterChain,
the code like this:
SocketAcceptor acceptor = new NioSocketAcceptor();
DefaultIoFilterChainBuilder chain = acceptor.getFilterChain();
ThreadPoolExecutor threadPool = new ThreadPoolExecutor(1000,2000,600L,
TimeUnit.SECONDS,new ArrayBlockingQueue<Runnable>(1000),new
ThreadPoolExecutor.CallerRunsPolicy());
int threadNum = threadPool.prestartAllCoreThreads();
chain.addLast("threadPool", new ExecutorFilter(threadPool));
...
then I use JMeter to test the server.
the JMeter parameters:
Thread Num: 600
Ramp-up Period(in Seconds):1
loop num: 1
the samper: tcp samper
timeout:5000
no dely: ture
and the test result almost is OK, but also has a lot of can not get
response ,like:

so I want to know how reduce the "java.net.ConnectException: Connection
refused", and improve the performance :
also I am not sure set the JMeter parameter Ramp-up Period(in Seconds): to 1
is suitable.
any suggestion, thanks!
