1470 Capacity Optimization

I need your advice on a 1470 capacity optimization. This is how it is setup at the moment:



I was following sk39555 and I ran 'fw ctl pstat' to check what's the current status. There it is:


System Capacity Summary:
Memory used: 17% (184 MB out of 1051 MB) - below watermark
Concurrent Connections: 1% (1632 out of 149900) - below watermark
Aggressive Aging is not active

Hash kernel memory (hmem) statistics:
Total memory allocated: 192937984 bytes in 47104 (4096 bytes) blocks using 21 pools
Initial memory allocated: 109051904 bytes (Hash memory extended by 83886080 bytes)
Memory allocation limit: 408944640 bytes using 512 pools
Total memory bytes used: 76512184 unused: 116425800 (60.34%) peak: 178943980
Total memory blocks used: 21151 unused: 25953 (55%) peak: 44215
Allocations: 84585497 alloc, 0 failed alloc, 83774180 free


The SK talks that the Total memory allocated should be roughly the same as Memory pool size in the Optimization property. Unless I calculate something wrong, at the moment it is ~192 MB which is much more than the 20 MB set as initial memory pool and the max mem pool size. In fact, it says it extended it by ~83MB which is kind of not recommended and may cause memory fragmentation.


So, what I am not getting right here ? Anything I should change/adjust ?
