Hi Googlers and GAE users,
I changed code little bit, there was one problem.And then i tried sedning a
message every 2 seconds and it went fine.
I think after this fix i will be able to get a speed of 80 messages/second,
but still far away from 3000/second.
i removed this line
* Chat chat = connection.getChatManager().createChat("
[email protected]", messgageHandler);
*from function sendToGae and then i could send messages faster. Now Chat
chat is my class variable and get created once in constructor . And after 1
message per 2 seconds i got curious and just ran the loop to send many
messages with out any delay and after sending 92 messages continuosly i got
Constraint response.It didnt say much about what constraint but i could send
90 messages in a row without delay.*
*
public void sendToGae(String message) throws XMPPException, MessageException
{
* Chat chat = connection.getChatManager().createChat("
[email protected]", messgageHandler);*//this line i removed
//messageHandler will receive the message back from server, if i receive
the
same mesage back that means my message did not reach server.If i receive
success, that means my message reached
chat.sendMessage(messageXml);
}
public void disconnect() throws XMPPException
{
connection.disconnect();
}}
