DistributedCacheService Consuming A lot of memory SP2013

Question

The Distributed Cache on our WFE is consuming too much memory (50% of the server, almost 6GB out of 12GB)

It seems like we have AppFabric 1.1

along with the other services it's consuming 95% of the server

i suspect the AppFabric is the problem because only the Search service has a higher consumption too (1.4GB)

how can I troubleshoot if we have a problem with the AppFabric, release its memory or configure it for a lower consumption.

Thank you

This is expected. How many concurrent users do you have utilizing the farm? You can use Update-SPDistributedCacheSize (https://docs.microsoft.com/en-us/powershell/module/sharepoint-server/update-spdistributedcachesize) to lower the allowed memory usage but if you set it too low, you may run into performance issues.
