Netcup vs Contabo: Why Developers Are Migrating to Netcup Root Servers (2026)

Real-world comparison of Netcup vs Contabo. Testing CPU steal rates, NVMe IOPS throttling, AMD EPYC Zen 5 dedicated cores, German datacenter ISO 27001 standards, and zero-downtime migration steps.

On paper, Contabo looks astonishingly cheap: 4 vCPU cores and 8 GB RAM for under €5 per month. But seasoned developers and sysadmins know the harsh reality: severe CPU steal, disk IOPS throttling dropping below 20 MB/s, and unexplained server freezes caused by extreme node overselling.

In contrast, Netcup Root Servers offer 100% dedicated AMD EPYC 9645 (Zen 5) hardware cores with strictly zero CPU steal, enterprise DDR5 ECC RAM, and over 320,000 IOPS. Here is why thousands of developers have migrated their databases and critical workloads from Contabo to Netcup.
