This is the first in a set of tuning posts.
I am going to start posting tuning parameters for different systems configurations.
This is for a Small memory < 4GB desktop. Specifically a 3GB laptop.
Don't use for a server, will be really bad. Obviously, there are network tuning parameters here and I presume NFS access/needs. These parameters are well documented on the internet, the why of my parameters, is really my secret sauce.
At a later date, I will describe the why and how of these configurations, but for now, paly if you wish.
Of course these drop in /etc/sysctl.conf.
net.ipv4.tcp_syncookies = 1
vm.min_free_kbytes = 200000
vm.swappiness = 0
vm.dirty_background_ratio = 1
vm.dirty_expire_centisecs = 1000
vm.dirty_ratio = 2
vm.dirty_writeback_centisecs = 250
vm.vfs_cache_pressure = 10000
vm.zone_reclaim_mode = 1
vm.laptop_mode = 0
