Message size

[vkalpias]

Hello,

I am trying to optimize our network messages and I was wondering if I can get a more detailed explanation on the overhead of each network message.

For instance I am sending a message to the server to synchronize a timer, which only contains a key and an empty SFS object. This is the dump of the message:

(int) r: -1
(utf_string) c: sc_t
(sfs_object) p:

Then the server responds with the same message and a long field that contains a timestamp. This message is sent using UDP and the smartfox log reports its size as 63 bytes. This seems like a lot to me because this is the message just contains a long field with a key = "t".

If I count the bytes without considering the overhead it should be close to:
key = "sc_t", size = 4 bytes
long field with key = "t", size = 8 bytes + 1 byte

This is 13 bytes total! Is the overhead of UDP 50 bytes?

Try turning on the debug feature on the client(*) and server side(**) to see exactly the content of the packets.
The overhead of UDP should be pretty small.

(*) by turning on the SmartFox.debug flag
(**) by editing config/log4j.properties file

Could you tell me what do I need to change in log4j.properties?
