Optimizations for FreeBSD
With this tutorial, I will explain to you how we can make our FreeBSD a little faster and optimize it for desktop usage.
Extend X11 interface for shared memory
$: doas nano /etc/sysctl.conf =>
kern.ipc.shmmax=67108864
kern.ipc.shmall=32768
We are configuring the scheduler for desktop use
$: doas nano /etc/sysctl.conf =>
kern.sched.preempt_thresh=224
We are increasing the maximum number of files open
$: doas nano /etc/sysctl.conf =>
kern.maxfiles=200000
Boot time kernel tuning
$: doas nano /boot/loader.conf =>
kern.ipc.shmseg=1024
kern.ipc.shmmni=1024
kern.maxproc=100000
Asynchronous I / O
$: doas nano /boot/loader.conf =>
aio_load="YES"
Thermal sensors
# Intel Core thermal sensors
$: doas sysrc -f /boot/loader.conf coretemp_load="YES"
# AMD thermal sensors
$: doas sysrc -f /boot/loader.conf amdtemp_load="YES"
Automatic fsck repair and fsck background (except for ZFS installation)
$: doas sysrc fsck_y_enable=YES
Deactivate the access time on our partition
By default, the time of access to files is noted, which can take time (and not used much). When we edit the /etc/fstab file, we add the noatime option:
$: doas nano /etc/fstab =>
#Device Mountpoint FSType Options Dump Pass
/dev/gpt/ROOT / ufs rw,noatime 1 1
Percentage of hard drive reserved
By default, FreeBSD reserves 8% of the hard drive for its system operations (defragmentation). If that's too much for us, we can change this value with this command:
$: doas tunefs -m X
We avoid creating a .core file
$: doas nano /etc/csh.login =>
limit coredumpsize 0
$: doas nano /etc/sysctl.conf =>
kern.coredump=0
