High memory utilization

[XFNeo]

Hi! I have high memory utilization after enabled Hyper Cache.
Before it was ~35% after it comes 80%
But when I check top or Process in TOS GUI utilization is still about 35%

Code: Select all

# free -m
              total        used        free      shared  buff/cache   available
Mem:           3761        2885          79         108         796         700
Swap:          1951         366        1585

Setu up:
F2-423
TOS 5.1.31, check with 5.1.33 also
2 NVME in RAID 0
4 Gb RAM

This is a normal situation that enabling SSD cache will consume a certain amount of TNAS memory.
You can make it smaller according to your needs.

How I can adjust it and where can I see the current consumption for hyper cache?

Isn't 40% of RAM too much for Hyper cache?

[TMzethar]

After you disable and re-enable Hyper Cache, you can choose the capacity again.

Could you explane me how is cache size on nvme disk related to RAM consumption? And what are the recommendations for cache size?

[TMtina]

The cache size on the nvme disk is not directly related to the RAM consumption. Normally, the larger the cache size of the nvme disk, the better.

How I can figure out how many RAM utilized by cache?

[TMtina]

You can use the command free -h to view RAM usage, including cached information.

You can use the command free -h to view RAM usage, including cached information.

This command does not show how many RAM exactly utilized by cache.
