At VM6 Networks, we are always looking for ways to improve performance, reliability, and the overall customer experience. As part of that commitment, we are moving away from Virtualizor and transitioning to VirtFusion.

This is more than just a control panel change. It allows us to make better use of modern CPU platforms such as the AMD Ryzen 9 9950X, improve how VPS resources are allocated, and deliver better and more consistent low-latency performance.

In short: VirtFusion gives us a more modern platform, better automation, and the ability to implement smarter CPU placement policies such as CCD-aware pinning on Ryzen 9950X nodes.

Why We Are Moving Away From Virtualizor

Virtualizor has been a familiar platform in the VPS industry for a long time, but modern hosting infrastructure now demands more flexibility, cleaner automation, and better support for newer hardware topologies.

While Virtualizor does support CPU pinning at a basic level, it is limited when it comes to automation and topology-aware placement. On modern Ryzen platforms, that matters a lot.

With Virtualizor, you can pin individual CPU cores, but doing so properly at scale is difficult to automate, and there is no practical built-in way to intelligently pin VPS instances by CCD groups. That means a VPS may end up spread in ways that are less than ideal for latency-sensitive workloads.

Why VirtFusion Is Better

VirtFusion gives us a much more modern platform to build on. It is cleaner, faster to work with, and better suited to the way modern VPS infrastructure is deployed and managed.

1. Better Automation

One of the biggest advantages of VirtFusion is automation. It gives us much more control over how VPS instances are deployed, scheduled, and managed. That means we can enforce better resource allocation policies across nodes without relying on manual work.

2. Better for Modern Hardware

Modern CPUs are no longer simple single-block processors. Architectures like the Ryzen 9950X have a layout that benefits from being understood and managed correctly. VirtFusion gives us the flexibility to build deployment logic around that.

3. Cleaner and More Modern Experience

VirtFusion provides a more modern interface and management experience for both the provider and the customer. That means a smoother panel, cleaner workflows, and a better long-term platform for VM6 Networks.

4. Better Long-Term Scalability

As we continue expanding and improving our infrastructure, we need a platform that lets us implement advanced optimisations consistently. VirtFusion is simply better suited to that future.

Why the Ryzen 9 9950X Performs Better on a Modern Kernel

The Ryzen 9 9950X is a very high-performance CPU, but like all modern processors, it performs best when the operating system and scheduler understand the hardware properly.

Newer kernels generally provide better support for modern CPU scheduling, cache awareness, topology handling, and platform improvements. On a modern Ryzen system, this helps ensure workloads are placed more intelligently and consistently.

In real-world VPS hosting, this matters because better scheduling means:

  • better cache locality
  • more consistent CPU behaviour under load
  • lower scheduling overhead
  • improved latency for performance-sensitive workloads

Put simply, the Ryzen 9950X is a strong CPU on its own, but it benefits even more when paired with a modern kernel and a virtualization platform that can take advantage of the CPU’s topology.

Understanding CCDs on the Ryzen 9950X

The Ryzen 9950X uses a chiplet design. Instead of all CPU cores sitting in one single block, the processor is split into separate groups of cores called CCDs (Core Complex Dies).

This is important because communication inside the same CCD is typically more efficient than bouncing workloads between CCDs. If a VPS is allowed to move across both CCDs, latency can increase and performance consistency can suffer, especially for workloads that care about cache locality and response times.

Why this matters: when a VPS stays inside one CCD, it avoids unnecessary cross-CCD movement. That helps reduce latency and can improve consistency for demanding workloads.

CCD Pinning vs Basic Core Pinning

Basic CPU pinning means assigning a VPS to specific CPU cores. That is useful, but on Ryzen it does not tell the whole story.

A VPS can be pinned to cores that are technically fixed, but if those cores are split across different CCDs, the VPS may still suffer from higher inter-CCD latency.

CCD-aware pinning goes further by keeping a VPS inside a specific CCD whenever possible. This ensures that the virtual CPUs stay within the same core group instead of being spread across both CCDs.

That is where VirtFusion gives us an advantage.

  • Virtualizor: core pinning is possible, but not well suited for automation, and CCD-aware placement is not practical to manage at scale.
  • VirtFusion: gives us a better foundation to automate smarter placement logic, including keeping VPS instances inside the same CCD.

What This Means for Customers

By moving to VirtFusion, VM6 Networks can build a more advanced and consistent hosting platform. This means we are better able to:

  • make better use of Ryzen 9950X hardware
  • improve CPU allocation policies
  • reduce unnecessary cross-CCD movement
  • deliver lower latency and more consistent performance
  • provide a cleaner and more modern management experience

A Better Control Panel Experience

Just as importantly, customers benefit from a cleaner day-to-day experience. A more modern VPS panel makes routine tasks quicker, easier to understand, and more reliable.

For customers running game servers, databases, web applications, trading tools, or other latency-sensitive services, these kinds of infrastructure improvements can make a real difference.

Final Thoughts

Moving from Virtualizor to VirtFusion is part of a wider effort to modernise the VM6 Networks platform. Virtualizor helped get the job done, but VirtFusion gives us a better long-term foundation for where our infrastructure is going.

Combined with modern kernels and Ryzen 9950X-based nodes, VirtFusion gives us the flexibility to implement smarter CPU placement, including CCD-aware pinning, which helps reduce latency and improve consistency for VPS workloads.

This is another step forward in delivering fast, modern, and performance-focused UK VPS Hosting at VM6 Networks.
