half of the original, too wasteful (solution: can be improved, not by 1 : 1 scale); (B), efficiency decreases with increased object survival More replication is required when the object has a high survival rate. The efficiency will be reduced (fix: The following markup-collation algorithm); 4. Application Scenario Now the commercial JVM uses this algorithm (by improving the disadvantage 1) to recover the Cenozoic; such as serial collectors, parnew col

. Net garbage collection and big object processing,. net garbage collection objects This article cited from: http://www.cnblogs.com/yukaizhao/archive/2011/11/21/dot_net_gc_large_object_heap.html The CLR Garbage Collector divides Objects Based on the occupied space. The proc

, for the long life cycle of the object, this traversal is not effective, because it may have been traversed many times , but they still exist. Therefore, the generational garbage collection uses the idea of divide and conquer, divides the generations, puts the objects of different life cycles on different generations, and uses the garbage

As the hardware continues to grow, Java Heap is growing, and reasonable garbage collection tuning becomes increasingly important. Here are some best practices:Attention: IBM AIX Java is not covered below. It also does not introduce the principle, just the recommendations and initial configuration/best practices, and how to iteratively optimize Need to understand the Java Virtual machine specifi

Chapter 5 JVM garbage collector (1): jvm garbage collection (The garbage collection algorithm is a theory, and the garbage collector is a collection algorithm. For details about the

Python memory management method and garbage collection algorithm parsing, python garbage collection Summary There is a circular reference problem in the list, tuples, instances, classes, dictionaries, and functions. Instances with the _ del _ method will be processed in a sound way. It is easy to add GC support for new

Class (2)-deconstruct function and garbage collection, deconstruct garbage collection After defining a class, we can create any number of objects. In this case, the memory allocation on the managed heap and stack will be generated, and a new space will be opened in the heap to store class objects, while the stack will

. Net garbage collection-Principle Analysis and. net garbage collection This article cited from: http://www.cnblogs.com/wilber2013/p/4357910.html During the development of. NET programs, since the garbage collection mechanism in

Objective PHP is a managed language, in PHP programming programmers do not need to manually handle the allocation and release of memory resources (using C to write PHP or Zend extensions), which means that PHP itself implements the garbage collection mechanism (garbage Collection). Now if you go to PHP official website

Objective:Think first about the three things you need to do with garbage collection (garbage COLLECTION,GC)1) What memory needs to be recycled?2) When is it recycled?3) How to recycle?The previous blog mentions the various parts of the Java Memory Runtime area, where the program counter, virtual machine stack, local me

reduces the point-to-point efficiency of the program. 5. Generational Collector) 　　The by-generation collection algorithm JVM divides the heap into the Young, Old, and Perm areas. The Young area is further divided into the Eden area and two vor areas. All newly created objects are in the Eden area, when the Eden area is full, minorGC will be triggered to copy th

We all know the Java garbage collection mechanism, Java has its own garbage collector to automatically recycle garbage. I have been aware of the garbage collection mechanism before the Java ga
