Memory cache and slow TrueNAS

[IBCMED]

Hey guys, all right? It has 64GB of DDR4 RAM on my TrueNAS and I am noticing that it is adding about 54GB just for cache, thus making the system slower than usual. As soon as I restart it, I have a lot of free memory and the system runs perfectly. Do you know how I can limit the cache? Is it normal that the more it accumulates cache, the slower it gets? Thanks in advance friends!

Cache is space that gets reclaimed by the OS if it's needed by other applications I don't think the problem is your cache taking up all the memory.
