Hi ! I'm developing a little Hub Server for Direct Connect Protocol (P2P), and I'm experiencing some big performance problems.
When I posted the first messages Niklas answered me that it could be the database which could block threads, so he told me that I had to use some O/R product like Hibernate. So I used Hibernate, performance with its cache and connection pooling mechanisms effectively are better, but no sufficient to be considered a good product. I'm searching for performance tips...So I have a question...but before a little example about the communication between client and server (a login handshake) clients connect...server sends a key and the hubname S: $Lock fdsjfsiodfjaiosdjfsaomfoos Pk=somekey| S: $HubName myhubname.mydomain.com| ... clients asks the server to validate the nick, sends his info and asks for the userlist: C: $Validate MyNick| C: $MyINFO $ALL MyNick iinfo....| C: $GetNickList| server answers with all the MyINFO of the connected users: S: $MyINFO $ALL user1 info...| S: $MyINFO $ALL user2 info...| S: $MyINFO $ALL user3 info...| S: $MyINFO $ALL user4 info...| S: $MyINFO $ALL user5 info...| ... S: $MyINFO $ALL user1000 info...| ... Now the question is, according to you it's better to write on the IoSession one single time with a big message or fragment the big message in more writes ? Then...now I tryied to use a threadPool of 10 elements in my overriden class of ServiceRegistry...what about this ? How can I tune this parameter ? What are the refs ? Best regards, Alessandro Torrisi
