1 fre—The size of your memory free list.

2 Determining the adjacency is easy because the free list is maintained in order of decreasing address.

3 fre—This column represents the size of your memory free list.

4 Finally, the free list represents the blocks that have been erased and are available for use.

5 It continues to do this until the free list has at least the number of pages in the maxfree parameter.

6 If the free list is not empty, the block at the head of the list is returned to the caller.

7 At the same time, VMM maintains a free list of unallocated page frames, which are used to satisfy page faults.

8 Low free list values might indicate that you have a lot of active RAM in use, which might trigger swap space use if you add more processes to the system.

9 VMM also maintains what is referred to as a free list, which is defined as unallocated page frames.

10 This paging algorithm determines which virtual memory pages currently in RAM ultimately have their page frames brought back to the free list.

11 However, more complicated uses of Simple Segregated Storage may require a sorted free list, which makes deallocation O(N).

12 AIX 7 uses all available memory, except memory that is configured to be unallocated and known as the free list.

13 The memory shows the amount of swap currently available and the size of the free list (the number of pages that could be swapped if the RAM were requested).

14 AIX uses all available memory, except that which is configured to be unallocated and known as the free list.

15 Memory deallocation may be as simple as adding that chunk to the front of the free list, a O(1) operation.

16 First, we significantly improved the way the runtime manages the free list, thereby making more effective use of fragments.

17 When the SSD receives this new command, it can add the blocks defined to its free list and no longer worry about moving them around as part of wear-leveling.

18 Free reports back the amount of pages on the free list.

19 The reason that is probably happening is because your free list (fre) is probably lower then the threshold for minfree, which you had given it using vmo.

20 USED and FREE columns list the total amount of memory from the used list and total amount of memory from the free list.

21 The VMM has a page-replacement algorithm, which assigns the page frames and determines exactly which virtual-memory pages currently in RAM will have their page frames brought back to the free list.

22 Furthermore, the AIX operating system will use all available memory, except that which is configured to be unallocated and known as the free list.
