# 2. 直接JMH性能测试比较
|
||
## 2.1 测试环境
|
||
* MacBook Pro (16-inch, 2021) MacApple M1 Max, 64GB Memory
|
||
* ZuluJDK
|
||
|
||
## 2.1.1 比较的版本
|
||
* Fastjson 2.0.1
|
||
* Fastjson 1.2.79
|
||
* Jackson 2.12.4
|
||
|
||
## 2.1.2 JDK版本
|
||
* JDK 8 zulu8.60.0.21-ca-jdk8.0.322-macosx_aarch64
|
||
* JDK 11 zulu11.54.25-ca-jdk11.0.14.1-macosx_aarch64
|
||
* JDK 17 zulu17.32.13-ca-jdk17.0.2-macosx_aarch64
|
||
|
||
## 2.2 Parse性能比较
|
||
* 测试代码 https://github.com/alibaba/fastjson2/blob/2.0.1/core/src/test/java/com/alibaba/fastjson_perf/eishay/EishayParse.java
|
||
|
||
|
||
### 2.2.1 场景介绍及结论
|
||
* EishayParseTreeString场景，将String解析成JSONObject/JSONArray或者HashMap/ArrayList。在这个场景，fastjson2表现出了两倍于fastjson1的性能
|
||
* EishayParseString场景，将String反序列化为JavaBean对象，在这个场景fastjson2相对于fastjson1性能提升了30%的性能。
|
||
* EishayParseStringPretty，将格式化带空格和换行符缩进的String反序列化为JavaBean对象，fastjson2在3.44倍于fastjson1。这个场景在fastjson1中是弱项，在fastjson2中采用新解析的算法，性能有了非常大提升。
|
||
* EishayParseUTF8Bytes，将UTF8格式的byte[]反序列化为JavaBean对象，
