Question Set limit cache memory

[Trung Ma]

Hello All,

I got a problem with cache memory. It always has around 85-95% physical memory.
[root@vzpl01 trung.ma]# free -m
total used free shared buff/cache available
Mem: 13312 1072 0 325 12239 12009
Swap: 0 0 0

How can I set the limit cache memory in Plesk Onyx 17.5 on VPS Centos 7?

Regards,
Trung Ma

Thank Mark, I read it before I posted this thread. Anyway, I want to set the limit cache memory around 50-60% of total physical memory.

I'm trying to understand the actual use purpose you're going for.... Putting a cap on it will just waste ram...
