KVM VPS-Festplatten-E/A-Optimierung, Netzwerkoptimierung

Beschränkt auf DuFu oder KVM VPS.

1. KVM VPS Disk I/O-Optimierung
Unter SSH:
1.

 echo 0 > /sys/block/vda/queue/rotational echo 0 > /sys/block/vda/queue/rq_affinity echo noop > /sys/block/vda/queue/scheduler echo "echo 0 > /sys/block/vda/queue/rotational" >> /etc/rc.local echo "echo 0 > /sys/block/vda/queue/rq_affinity" >> /etc/rc.local echo "echo noop > /sys/block/vda/queue/scheduler" >> /etc/rc.local echo 'vm.swappiness=5' >> /etc/sysctl.conf echo 'vm.vfs_cache_pressure=50' >> /etc/sysctl.conf

2.

 sysctl -p

3. Ändern Sie fstab

 vi /etc/fstab proc /proc proc defaults 0 0 # / was on /dev/sda1 during installation UUID=bf175032-898a-4883-a702-ca0ab9e51d1d / ext4 noatime,errors=remount-ro 0 1 # swap was on /dev/sda5 during installation UUID=2d7209ed-b4c1-4bb6-96f2-73d7ba82ca9b none swap sw 0 0 /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0

4.

 mount -o remount /

2. KVM VPS-Netzwerkoptimierung
