Engineering Analysis & Comparison FAQ

Real-world trade-offs between dedicated AMD EPYC cores, unmetered fair-use bandwidth, and competitor cloud features.

OversellingWhy does Netcup exhibit zero CPU Steal compared to Contabo?

Contabo employs aggressive hypervisor vCore oversubscription, causing CPU Steal between 15% and 35% during peak hours. Netcup Root Servers provide 100% dedicated hardware threads, maintaining strictly 0.0% CPU Steal.

Storage IOPSHow does NVMe storage performance compare between Contabo and Netcup?

Contabo throttles storage to ~15,000–35,000 IOPS. Netcup Root Servers reach over 187,000 IOPS in FIO 4K tests, offering 6x to 8x higher responsiveness for database engines.
