Application fabric – DistributedCacheService Consuming Lots of memory SP2013

The cache distributed in our WFE consumes too much memory (50% of the server, almost 6 GB of 12 GB)

It seems we have AppFabric 1.1

Along with the other services, it consumes 95% of the server.

I suspect that AppFabric is the problem because only the search service has a higher consumption (1.4 GB)

How can I solve problems if we have a problem with the AppFabric, free up its memory or configure it for less consumption?

Thank you
