Enhance your FreeBSD server's performance with these optimization techniques
Edit /boot/loader.conf and /etc/sysctl.conf to optimize kernel settings:
# /boot/loader.confkern.ipc.shm_allow_removed=1kern.ipc.somaxconn=4096net.inet.tcp.sack.enable=1 # /etc/sysctl.confkern.maxfiles=200000kern.maxfilesperproc=150000net.inet.tcp.sendspace=262144net.inet.tcp.recvspace=262144
Add to /etc/sysctl.conf:
kern.elf64.aslr.enable=1kern.elf32.aslr.enable=1
Edit /etc/fstab and add the async option to non-critical partitions:
/dev/ada0p2 /home ufs rw,async 2 2
Adjust ARC (Adaptive Replacement Cache) size:
# /boot/loader.confvfs.zfs.arc_max="4G"
Add to /etc/rc.conf:
ifconfig_em0="SYNCDHCP txcsum rxcsum tso lro"
Add to /etc/sysctl.conf:
net.inet.tcp.sendbuf_max=16777216net.inet.tcp.recvbuf_max=16777216
Add to /etc/sysctl.conf:
kern.ipc.shmmax=1073741824Add to /etc/sysctl.conf:
vm.swappiness=10
Edit /usr/local/etc/nginx/nginx.conf:
Edit /var/db/postgres/data13/postgresql.conf:
These optimizations are general guidelines. Always test thoroughly in a non-production environment before applying to your live server. Some settings may need to be adjusted based on your specific hardware and workload.
