2. Dedicated Cores & 0% CPU Steal: 24/7 Sustained Load

🎯 Why Developers Rely on Netcup Root Servers:

Unlike regular cloud providers who dynamically overcommit vCPUs across neighbors, Netcup Root Server locks dedicated AMD EPYC 9645 physical cores to your virtual machine via kernel-level CPU pinning. Even during multi-day 100% compute runs (compiling, rendering, game hosting), your CPU steal stays at 0.0%.

0.0% CPU Steal

Measured with sysbench and stress-ng: %st steal time remains 0.0% under full load with zero noisy-neighbor degradation.

AMD EPYC 9645 (Zen 5)

Leading-edge Zen 5 server architecture with massive L3 cache and exceptional single-threaded and multi-threaded IPC.

100% Sustained Load Allowed

Officially approved for 24/7 continuous 100% CPU utilization without unexpected throttling or account suspension.

3. Virtualization & Custom ISO (No Nested KVM / Container Focus)

Key architectural clarifications regarding virtualization capabilities on Netcup Root Servers:

⚠️No Hardware Nested KVM

Netcup does not pass through AMD-V/SVM hardware flags to guest instances (reported as Disabled). Hardware-accelerated nested KVM virtual machines cannot run. However, kernel-based container technologies (Docker, Podman, LXC) run at 100% native bare-metal speed.

💿Custom ISO Mount & HTML5 VNC

Mount custom operating system ISOs (FreeBSD, Alpine, Windows Server, Arch Linux) directly via HTTP URL in the virtual DVD drive and control installations via the browser HTML5 VNC console.

4. Competitor Benchmark: Root Server vs Bare-Metal & Dedicated Cloud

Direct architectural comparison between Netcup RS 1000 G12 and equivalent dedicated cloud and bare-metal servers:

💎 Value Analysis & Verdict:

Netcup Root Server combines the uncompromised raw throughput of dedicated bare-metal hardware (zero CPU steal) with modern cloud perks (zero setup fee, instant snapshots, web VNC) at a fraction of the cost of Hetzner dedicated cloud or AWS EC2.

5. Pros, Cons & Ideal Workloads

✅ Recommended Workloads
  • Production databases requiring high sustained I/O and dedicated CPU (MySQL, PostgreSQL, Redis).
  • Continuous integration and build pipelines (GitLab Runner, self-hosted GitHub Actions).
  • Dedicated game servers demanding high single-core clocks (Minecraft, Palworld, CS2, Rust).
  • High-density microservices running natively on Docker, Podman, or LXC containers.
⚠️ Trade-offs & Limitations
  • Higher monthly base price than shared VPS due to dedicated physical core isolation.
  • For additional raw storage, Netcup Block Storage volumes can be attached.

6. Frequently Asked Questions (FAQ)

Q:Can I really run 100% CPU load 24/7 without being throttled or suspended?

Yes, completely! That is the core value proposition of Netcup Root Servers. Physical AMD EPYC cores are pinned 1-to-1 to your instance via hypervisor CPU pinning. You are contractually entitled to run 100% sustained compute 24/7/365 without throttling, penalties, or noisy neighbors.

Q:Does Root Server support hardware-assisted nested virtualization (KVM)?

No, hardware-level nested virtualization is explicitly not supported. While Root Server instances enjoy 1:1 dedicated AMD EPYC cores and 0% CPU steal, Netcup disables hardware virtualization flag passthrough (AMD-V / SVM / VT-x) on the host hypervisor. Consequently, secondary hardware-accelerated KVM virtual machines cannot run. However, container-level isolation—including Docker, Podman, and Proxmox LXC containers—runs natively at full hardware speed.

Q:Can I boot and install from custom ISO images via SCP?

Yes. In the Server Control Panel (SCP), you can mount custom ISO images by pasting an HTTP/HTTPS direct URL or uploading via FTP. Boot into any OS including FreeBSD, Alpine Linux, Proxmox VE, or custom Windows Server, and manage the setup via the HTML5 VNC console.

Q:What is the fundamental architectural difference between Root Server and regular VPS?

Standard VPS instances use shared vCores balanced across neighbor workloads. Root Servers feature dedicated 1:1 hardware core pinning (AMD EPYC 9645), guaranteed zero CPU steal, native Docker/LXC isolation, and prioritized hardware SLA under continuous heavy workloads.

Q:Are free instant snapshots included with Root Server plans?

Yes. Just like the VPS series, Root Server plans include up to 4 free instantaneous snapshot slots in the Server Control Panel. Create crash-consistent snapshots online before risky system modifications and roll back in seconds if needed.

Q:What are the bandwidth and throttling policies for Netcup Root Servers? Are there overage fees?

Zero overage penalties (100% predictable €0 excess fees)! Standard 2.5 Gbps port throttle rule: if average network traffic over the past 24 hours exceeds 3 TB, the system temporarily throttles the port to 300 Mbps, which is automatically lifted once the 24-hour condition is no longer met. For Singapore location (1 Gbps port): up to 1 Gbps port speed within an included 3 TB traffic allowance; once 3 TB is reached, speed is throttled to 5–20 Mbps for the remainder of the month.
