Greatly, internal memory of new generation is always easy for completely, and old generation is very empty, and the Cenozoic always completely always causes Memory recycle of new generation, shadow
The performance of java application is rung.
Now, user can will distribute to neozoic heap and be adjusted to 1.5G, and the heap for distributing to old generation is adjusted
Whole is 0.5G.Judge java application on startup that is, Memory Allocation information and internal memory heapinfo are used for user
Whether whether the configuration of Memory Allocation relevant parameter is reasonable, i.e., because the unreasonable allocation of Memory Allocation relevant parameter, and influence
The performance of java application, if (although i.e. actual memory allocation of parameters is identical with default Memory Allocation parameter, in advance
If Memory Allocation parameter is simultaneously unreasonable), then according to the characteristics of java application, Memory Allocation relevant parameter is changed, and again
Start java application, Memory Allocation relevant parameter is configured to amended parameter.
For memory object statistical information：Memory object statistical information includes committed memory depositing at most and without release
Object living.User can search the program word for including the survival object according to the survival object that Memory recycle statistical information includes
Whether sentence is problem program sentence, if so, then illustrating that the program statement for including the survival object have impact on java application
Performance.
