Hello, C1V Hosting enthusiasts! We're here to bring you another tech-savvy article to enhance your hosting experience. Today, we're diving into the world of VPS KVM tunings to turbocharge your virtual server's disk speed.

At C1V Hosting, we're all about squeezing every bit of performance out of our infrastructure, and you should be too. So, without further ado, let's explore some configuration tweaks that can make a substantial difference.

Optimizing Disk Performance

For an official ISO Install, follow these commands to tweak your Linux MyCore VPS:

• Set rotational to 0: /sys/block/sda/queue/rotational
• Set rq_affinity to 0: /sys/block/sda/queue/rq_affinity
• Use the noop scheduler: /sys/block/sda/queue/scheduler
• Add these lines to /etc/rc.local:
  • echo 0 > /sys/block/sda/queue/rotational
  • echo 0 > /sys/block/sda/queue/rq_affinity
  • echo noop > /sys/block/sda/queue/scheduler
• Adjust virtual memory settings:
  • echo 'vm.swappiness=5' >> /etc/sysctl.conf
  • echo 'vm.vfs_cache_pressure=50' >> /etc/sysctl.conf
• Reload sysctl settings: sysctl -p

These commands optimize your VPS for disk speed by reducing latency and ensuring that the right I/O scheduler is in place.

Boosting Network Performance

To potentially enhance network performance, consider the following configurations:

• Increase receive and send buffer sizes:
  • echo "net.core.rmem_max=16777216" >> /etc/sysctl.conf
  • echo "net.core.wmem_max=16777216" >> /etc/sysctl.conf
• Adjust TCP receive and send memory:
  • echo "net.ipv4.tcp_rmem=4096 87380 16777216" >> /etc/sysctl.conf
  • echo "net.ipv4.tcp_wmem=4096 65536 16777216" >> /etc/sysctl.conf
• Reload sysctl settings: sysctl -p

These adjustments optimize your VPS for network traffic, ensuring smoother data flow and reducing bottlenecks.

Extra Performance Gains

As a bonus, you can further fine-tune your system's performance by adding the following options to your mounting setup in /etc/fstab:

• noatime
• nobarrier

For ext filesystems, use barrier=0 instead of nobarrier. To apply these changes without rebooting, you can use the mount command with the -oremount option.

By applying these VPS KVM tunings, you're on your way to unlocking the full potential of your virtual server. At C1V Hosting, we're committed to providing you with the best hosting experience, and these optimizations are just one way we ensure your server runs at peak performance.
