Application Structure – DistributedCacheService Consumes a lot of memory SP2013

The cache distributed on our front-end Web server is using too much memory (50% of the server, almost 6 GB on 12 GB)

It seems we have AppFabric 1.1

with other services, it consumes 95% of the server

I suspect that it is AppFabric that is problematic because only the search service also has a higher consumption (1.4 GB).

How can I fix the problem if we encounter a problem with AppFabric, let's free up its memory or configure it for lower consumption?

Thank you
