SolusVM sets the network card as Realtek, which is limited to 100Mbit, you should switch to Intel PRO/1000 if running Windows and Virtio on most Linux distributions.
Additionally you can run the following commands to make a few more tweaks in Linux:
echo net.core.rmem_max=16777216 >> /etc/sysctl.conf
echo net.core.wmem_max=16777216 >> /etc/sysctl.conf
echo net.ipv4.tcp_rmem=4096 87380 16777216 >> /etc/sysctl.conf
echo net.ipv4.tcp_wmem=4096 65536 16777216 >> /etc/sysctl.conf
Then to apply changes, run the following command:
sysctl -p
We recommend that you use the following DNS Servers from Google:
IPv4:
8.8.8.8
8.8.4.4
IPv6:
2001:4860:4860::8888
2001:4860:4860::8844
Optimizing Disk I/O:
soulsvm KVM setup of Linux usually doesn't include any tweaks, so here are some tweaks to improve I/O performance; as soon as you get your VPS you should go into SolusVM and under Settings change the disk driver from IDE to Virtio, you'll be required to reboot for changes to take effect.
Inside Linux you can also run the following commands to improve I/O performance:
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
Then to apply changes, run the following command:
sysctl -p
