[I] 2.8.4版本 性能优化分析 [servicecomb-java-chassis]

yanghao605 opened a new issue, #4054:
URL: https://github.com/apache/servicecomb-java-chassis/issues/4054

   2.8.4版本中使用PriorityProperty保存每一个operation对应的配置项，且是初始化的时候就会生成。
   动态加载的相关配置项由OperationConfig中定义，如：

   这就导致一个operation会对应10+PriorityProperty对象，PriorityProperty中包含了一个PropertyType和一个DynamicProperty数组

   最终会导致SDK中的内存占用会随着operation的数量以十几倍的比例进行增长。

   缺陷：会随着实际调用的operation增多而增多
