是我重新做测试的时候搞错了，我做的测试比较如下：

我新作的测试如下：
Decode 
EishayDecode	fastjson	3,236	YoungGC 17	FullGC 0
EishayDecode	fastjson	1,520	YoungGC 12	FullGC 0
EishayDecode	fastjson	1,537	YoungGC 26	FullGC 0
EishayDecode	fastjson	1,530	YoungGC 35	FullGC 0
EishayDecode	fastjson	1,535	YoungGC 22	FullGC 0

EishayDecode	jsonconvert	2,174	YoungGC 18	FullGC 0
EishayDecode	jsonconvert	2,026	YoungGC 37	FullGC 0
EishayDecode	jsonconvert	1,996	YoungGC 13	FullGC 0
EishayDecode	jsonconvert	2,014	YoungGC 20	FullGC 0
EishayDecode	jsonconvert	2,000	YoungGC 14	FullGC 0

EishayDecode	jackson 	4,987	YoungGC 50	FullGC 0
EishayDecode	jackson 	4,474	YoungGC 73	FullGC 0
EishayDecode	jackson 	4,456	YoungGC 57	FullGC 0
EishayDecode	jackson 	4,469	YoungGC 42	FullGC 0
EishayDecode	jackson 	4,437	YoungGC 13	FullGC 0


从这个测试来看，decode的性能，jsonconvert-0.1.0的性能和fastjson相差30%左右，比jackson快一倍以上。

测试的案例在上一个帖子中，这是我做的测试，你重新测试一遍，看我的测试是否有问题。



jvm-serializers 有使用文档么， 没用过~

我已经把https://github.com/eishay/jvm-serializers/的测试剥离出来了。你可以自己直接测试。

测试代码在这里：
http://code.alibabatech.com/svn/fastjson/trunk/fastjson/src/test/java/data/

包含3个java bean:MediaContent、Media、Image三个类。 

package data.media;

import java.util.List;

@SuppressWarnings("serial")
public class MediaContent implements java.io.Serializable
{
	public Media media;
	public List<Image> images;

	public MediaContent() {}

	public MediaContent (Media media, List<Image> images) {
		this.media = media;
		this.images = images;
	}

	@Override
	public boolean equals(Object o)
	{
		if (this == o) return true;
		if (o == null || getClass() != o.getClass()) return false;

		MediaContent that = (MediaContent) o;

		if (images != null ? !images.equals(that.images) : that.images != null) return false;
		if (media != null ? !media.equals(that.media) : that.media != null) return false;

		return true;
	}

	@Override
	public int hashCode()
	{
		int result = media != null ? media.hashCode() : 0;
		result = 31 * result + (images != null ? images.hashCode() : 0);
		return result;
	}

	public String toString() {
		StringBuilder sb = new StringBuilder();
		sb.append("[MediaContent: ");
		sb.append("media=").append(media);
		sb.append(", images=").append(images);
		sb.append("]");
		return sb.toString();
	}

    public void setMedia(Media media) {
        this.media = media;

构造对象的代码：

media.width = 640;
media.height = 480;
media.format = "video/mpg4";
media.duration = 18000000;
media.size = 58982400;
media.bitrate = 262144;
media.persons = Arrays.asList("Bill Gates", "Steve Jobs");
media.player = Player.JAVA;
media.copyright = null;

content.setMedia(media);

List<Image> images = new ArrayList<Image>();
{
    Image image = new Image();
    image.setUri("http://javaone.com/keynote_large.jpg");
    image.setTitle("Javaone Keynote");
    image.setWidth(1024);
    image.setHeight(768);
    image.setSize(Size.LARGE);
    images.add(image);
}
{
    Image image = new Image();
    image.setUri("http://javaone.com/keynote_small.jpg");
    image.setTitle("Javaone Keynote");
    image.setWidth(320);
    image.setHeight(240);
    image.setSize(Size.SMALL);
    images.add(image);
}
content.setImages(images);


输出的JSON文本 
{"images":[{"height":768,"size":"LARGE","title":"Javaone Keynote","uri":"http://javaone.com/keynote_large.jpg","width":1024},{"height":240,"size":"SMALL","title":"Javaone Keynote","uri":"http://javaone.com/keynote_small.jpg","width":320}],"media":{"bitrate":262144,"duration":18000000,"format":"video/mpg4","height":480,"persons":["Bill Gates","Steve Jobs"],"player":"JAVA","size":58982400,"title":"Javaone Keynote","uri":"http://javaone.com/keynote.mpg","width":640}}

输出的JSON文本

澳~   你这个MediaContent对象我的附件测试代码里面有， 构建的对象是468个字符。com.tencent.tendon.convert.jsontest.github.MediaContent   ， 类里面有main方法， 执行的结果跟你的结果还是有点差别， 我在linux上执行的结果比fastjson快50% ， 你的结果却是比我快30%， 不知道是不是环境问题~

建议你使用maven组织工程，否则要做测试麻烦一些，我相信别人也会有同感。

jvm在非windows环境下默认都是 -server模式运行， 加不加都一样。 我的也是1.6.0_26
不习惯把工程文件放到svn上。  不用maven好多年了，

温少的fastjson挺好的，希望可以努力接受jsonconvert的挑战！

先给你一个良好贴

之前我测试过jsonconvert-0.1.0beta版本，性能还可以，比jackson稍微差一些。

我想重新测试一遍，发现jsonconvert-0.1.0跑不过测试了。报错信息如下： 

jsonconvert-
com.tencent.tendon.convert.json.JsonException: a json object text must begin with '{' (position = 1)
	at com.tencent.tendon.convert.json.JsonDefaultReader.checkObject(Unknown Source)
	at com.tencent.tendon.convert.json.JsonDefaultToken.convertFrom(Unknown Source)
	at com.tencent.tendon.convert.json.JsonTokens$JsonSimpleArrayToken.convertFrom(Unknown Source)
	at com.tencent.tendon.convert.json.JsonTokens$JsonSimpleArrayToken.convertFrom(Unknown Source)
	at com.tencent.tendon.convert.json.JsonConvert.convertArrayFrom(Unknown Source)
	at com.tencent.tendon.convert.json.JsonConvert.convertArrayFrom(Unknown Source)
	at com.alibaba.json.test.codec.JsonConvertCodec.decodeObject(JsonConvertCodec.java:21)
	at com.alibaba.json.test.benchmark.decode.EishayDecode.execute(EishayDecode.java:24)


由于错误发生，测试无法继续，拿不到性能数据，这次没办法作比较。

你自己的测试程序比较片面，我建议你使用更综合场景做测试。

比如说https://github.com/eishay/jvm-serializers/提供的测试。不过那有点麻烦，我已经剥离了其中的测试代码。在这里：
http://code.alibabatech.com/svn/fastjson/trunk/fastjson/src/test/java/data/media/

是一个这样的JSON文本： 
{"images":[{"height":768,"size":"LARGE","title":"Javaone Keynote","uri":"http://javaone.com/keynote_large.jpg","width":1024},{"height":240,"size":"SMALL","title":"Javaone Keynote","uri":"http://javaone.com/keynote_small.jpg","width":320}],"media":{"bitrate":262144,"duration":18000000,"format":"video/mpg4","height":480,"persons":["Bill Gates","Steve Jobs"],"player":"JAVA","size":58982400,"title":"Javaone Keynote","uri":"http://javaone.com/keynote.mpg","width":640}}


构建测试的代码： 
MediaContent content = new MediaContent();

Media media = new Media();
media.uri = "http://javaone.com/keynote.mpg";
media.title = "Javaone Keynote";
media.width = 640;
media.height = 480;
media.format = "video/mpg4";
media.duration = 18000000;
media.size = 58982400;
media.bitrate = 262144;
media.persons = Arrays.asList("Bill Gates", "Steve Jobs");
media.player = Player.JAVA;
media.copyright = null;

content.setMedia(media);

List<Image> images = new ArrayList<Image>();
{
    Image image = new Image();
    image.setUri("http://javaone.com/keynote_large.jpg");
    image.setTitle("Javaone Keynote");
    image.setWidth(1024);
    image.setHeight(768);
    image.setSize(Size.LARGE);
    images.add(image);
}
{
    Image image = new Image();
    image.setUri("http://javaone.com/keynote_small.jpg");
    image.setTitle("Javaone Keynote");
    image.setWidth(320);
    image.setHeight(240);
    image.setSize(Size.SMALL);
    images.add(image);
}
content.setImages(images);


有竞争才有进步，希望你能够把jsonconvert做得够好！希望你使用maven仓库发布jar和sources.jar，那样测试更方便一些。



温少真现身了，支持温少

这样很好啊. 有竞争才会推动技术的进步. 支持温少和nbzhang, 希望你们给我们带来越来越好的json库, 同时二位大老能否另外开篇讲述一下二者的设计, 及为什么会比别家的快. 谢谢!!

fastjson已经到1.13了，比较全面了，正式使用也基本没什么问题。
jsonconvert才刚出来，文档和功能可能都还不能满足。
在性能和功能方面，我肯定会优先考虑功能是否能满足我的需求，再考虑性能。
希望两个Json Parser会更好。
