Hi,
I am doing my testing on server. I open 150 concurrent sessions. However, my
server CPU useage reaches 20% and memory is increasing 300M(increasing).
Also I got a Exception: Java.lang.OutOfMemoryError: Direct buffer memory.
at java.nio.Bits.reserveMemory
I also observed that lots of packets were lost at the client side.
Actually in my server, I just simply broadcast the data to clients. (I wrote
my own protocol codec filter, I use one session on instance method)
public void onBroadcasting(AbstractMessage message)
{
synchronized(sessions)
{
for (Enumeration e = sessions.elements(); e.hasMoreElements();)
{
IoSession session = (IoSession)e.nextElement();
session.write(message);
}
}
}
Did I miss something? Kinda desperate at this moment about the testing
results.
