sysctl settings to reduce buffers and caches in Linux
vm.swappiness = 1
vm.vfs_cache_pressure = 800
vm.dirty_ratio = 5
vm.dirty_background_ratio = 2
vm.min_free_kbytes = 65536 # Reserve 64MB for emergencies
This is mainly useful for smaller systems/VMs/dev test/Raspberry Pi etc.. but even servers with huge amounts of RAM can start putting a ton of things into buffers and cache especially if you open large files constantly.
