fastjson Benchmark

在fastjson-1.2.11中，序列化性能有了很大提升，反序列化性能也有所提升，所以做一次和其他序列化庫的性能對(duì)比測試。

測試場景

采用各個(gè)序列化庫作者都比較認(rèn)可的一個(gè)測試，來自 https://github.com/eishay/jvm-serializers，由于官方的測試還沒采用最新版本的fastjson，所以我fork修改使用最新的api，代碼在這里https://github.com/wenshao/jvm-serializers/tree/fastjson-1.2.11

運(yùn)行測試

git clone https://github.com/wenshao/jvm-serializers.git
cd jvm-serializers/tpc
make
./run-bench.sh json/jackson+afterburner/databind,json/fastjson/databind,json/fastjson_array/databind,protobuf,json/jackson/databind,msgpack/databind

類結(jié)構(gòu)

eishay的場景，有三個(gè)類，類結(jié)構(gòu)如下

class MediaContent {
    public Media media;
    public Image[] images;
}
class Media implements java.io.Serializable {
    public enum Player { JAVA, FLASH }
    public String       uri;
    public String       title;     // Can be unset.
    public int          width;
    public int          height;
    public String       format;
    public long         duration;
    public long         size;
    public boolean      hasBitrate;
    public List<String> persons;
    public Player       player;
    public String       copyright; // Can be unset.
}

class Image {
    public enum Size { SMALL, LARGE }
    public String uri;
    public String title; // Can be null
    public int    width;
    public int    height;
    public Size   size;
}

詳細(xì)代碼看這里：

• https://github.com/wenshao/jvm-serializers/blob/fastjson-1.2.11/tpc/src/data/media/MediaContent.java
• https://github.com/wenshao/jvm-serializers/blob/fastjson-1.2.11/tpc/src/data/media/Media.java
• https://github.com/wenshao/jvm-serializers/blob/fastjson-1.2.11/tpc/src/data/media/Image.java

測試數(shù)據(jù)

測試的場景是media.1.cks，對(duì)應(yīng)的json如下

{"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}}

fastjson中，如果啟用BeanToArray模式，對(duì)應(yīng)的json為：

[[[768,1,"Javaone Keynote","http://javaone.com/keynote_large.jpg",1024],[240,0,"Javaone Keynote","http://javaone.com/keynote_small.jpg",320]],[262144,null,18000000,"video/mpg4",480,["Bill Gates","Steve Jobs"],0,58982400,"Javaone Keynote","http://javaone.com/keynote.mpg",640]]

參與測試各個(gè)庫的版本

fastjson-1.2.11
jackson-2.7.0
protobuf-java-2.3.0.jar
