一、测试条件(LoadRunner)            

（1）测试并发人数：20人（有聚集点）

（2）事务完成的思考时间：1s
（3）一个事务包含4次请求（一个完整的同步过程）
（4）持续时间：30分钟
（5）联系人数量：350    
（6）硬件环境（虚拟机）：
     CentOS5（2.6.18-164.el5内核）
     4G内存
     双核CPU
                    
二、测试结果
top观察服务器的状态：
vcard：60%-80%
json:20%-30%
protobuf:7%-10%（因为protobuf转换成字符串之后又特殊字符，
                 在xml中无法解析，故加入base64的加解码，
                 同时数据传输也会减低很多）
                
三、优化
对json，只要按照JSONArray的字符串格式传输即可。
对于protobuf，需要定义自己的proto文件，如下：

// See README.txt for information and build instructions.

package com.test.pim.common;

option java_package = "com.test.pim.common";
option java_outer_classname = "ContactProtos";

message Contact {
    optional Name name = 1;
	optional Organization org = 2;
	repeated PhoneEntry phones = 3;
	repeated EmailEntry emails = 4;
	repeated WebPageEntry webpages = 5;
	repeated AddressEntry addresses = 6;
	repeated OnlineMessageEntry onlineMessages = 7;
	repeated string groups = 8;
	repeated string notes = 9;
	optional string birthday = 10;
	
	//Name Definition
	message Name {
		optional string firstName = 1;
		optional string middleName = 2;
		optional string lastName = 3;
		optional string suffix = 4;
		optional string prefix = 5;
		optional string nickName = 6;
	}
	
	//Organization Definition
	message Organization {
		optional string company = 1;
		optional string department = 2;
		optional string jobTitle = 3;
	}
	
	//Phone Definition
	message PhoneEntry {
	  enum PhoneType {
			MOBILE = 0;
			HOME = 1;
			WORK = 2;
			WORKFAX = 3;
			HOMEFAX = 4;
			OTHERFAX = 5;
			OTHER = 6;
			CAR = 7;
			ISDN = 8;
			CUSTOM = 9;
		}
	  optional string label = 1;
	  required PhoneType type = 2 [default = MOBILE]; 
	  required string value = 3;
	}
	
	//Email Definition
	message EmailEntry {
	  enum EmailType {
			HOME = 0;
			WORK = 1;
			OTHER = 2;
			CUSTOM = 3;
		}
	  optional string label = 1;
	  required EmailType type = 2 [default = HOME]; 
	  required string value = 3;
	}
	
	//WebPage Definition
	message WebPageEntry {
	  enum WebPageType {
			HOME = 0;
			BLOG = 1;
			WORK = 2;
			OTHER = 3;
			CUSTOM = 4;
		}
	  optional string label = 1;
	  required WebPageType type = 2 [default = HOME]; 
	  required string value = 3;
	}
  
	//Address Definition
	message AddressEntry {
	  enum AddressType {
			HOME = 0;
			WORK = 1;
			OTHER = 2;
			CUSTOM = 3;
		}
	  optional string label = 1;
	  required AddressType type = 2 [default = HOME]; 
	  required AddressExtend value = 3;
	}
	message AddressExtend {
		optional string street = 1;
		optional string city = 2;
		optional string state = 3;
		optional string postcode = 4;
		optional string country = 5;
	}
	
	//OnlineMessage Definition
	message OnlineMessageEntry {
	  enum OnlineMessageType {
			QQ = 0;
			MSN = 1;
			SKYPE = 2;
			GOOGLETALK = 3;
			AIM = 4;
			YAHOO = 5;
			ICQ = 6;
			JABBER = 7;
		}
	  optional string label = 1;
	  required OnlineMessageType type = 2 [default = QQ]; 
	  required string value = 3;
	}
}

数据构造发送代码：

 ContactProtos.Contact.Builder contact =
 ContactProtos.Contact.newBuilder();
 contact.setName(ContactProtos.Contact.Name.newBuilder().setLastName("testProtobuf").build());
 contact.addPhones(ContactProtos.Contact.PhoneEntry.newBuilder().setType(ContactProtos.Contact.PhoneEntry.PhoneType.HOME)
				 .setValue("425900").build());
				 contact.addPhones(ContactProtos.Contact.PhoneEntry.newBuilder().setType(ContactProtos.Contact.PhoneEntry.PhoneType.MOBILE)
				 .setValue("13163209158").build());
 byte[] encode = Base64.encode(contact.build().toByteArray());
 xml.append(new String(encode, "UTF-8"));

服务端解析代码：

ContactProtos.Contact c = ContactProtos.Contact.parseFrom(Base64.decode(data.getData().getBytes("UTF-8")));
