CPU consumption on a JSON JAVA application -


on quad core cpu machine 4 gb ram, tomcat 6 installed, java 1.6. have software handles communication gateway. handles incoming json messages using jersey (1.19), deserialize , call client send message server using jersey (1.19) rest libraries. handles incoming request other server, serialize json , send outside. 10 users connected, sending 600 byte of message every 4 seconds. global cpu consumption reaches 30%. normal expected behaviour? how can handle more users?

code:

private string executetogameengine(string text, string urlresource){ clientresponse response = null; try {              clientconfig clientconfig = new defaultclientconfig();   client client = client.create(clientconfig);   webresource webresource = client.resource(urlresource);    response =       webresource           .accept(mediatype.text_plain)           .type(mediatype.text_plain)           .post(clientresponse.class, text);    if (response == null) {     // error...   }   else if (response.getstatus() != 200) {                             // error...   }   return response.getentity(string.class);

}

we installed visualvm analyze problem, suggestion?enter image description here

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
