VM Settings

The goal for virtual memory settings is to make latency lower for better responsive and experience.

I've set dirty settings to lower value, make it write back to disk faster for more free memory instead of keeping it in memory for a longer time and caused I/O botttleneck when flush a large dirty pages to disk.

Dirty ratio: 15
Dirty background ratio: 3
Dirty expire centisecs: 500
Dirty writeback centisecs: 100
Minfree kbytes: 4096
Overcommit ratio: 50
Swappiness: 0
VFS cache pressure: 50
