[QUESTION] 反序列化JSON数组性能问题

[wangpeix]

从火焰图观查到JSONArray logs = JSON.parseArray(byte[] message)一步时耗费CPU，如下:

帮看下还有优化空间吗?

jdk版本: 8 fastjson版本: 2.0.48

大概是怎样的一个JSON结构？

大概是怎样的一个JSON结构？

一条数据是一个JSON数组: [{19个字段，是基本数据类型； 无嵌套},{}, {}...]

一个JSON数组大概120kb。

可以提供一个样本么？

可以提供一个样本么？ 类似这样

[wangpeix]

@wenshao 会不会是因为有中文导致性能变差了

[wenshao]

可以提供文本么，不要让我手工录入一遍哈
