Virtuozzo Containers™ Outperform Hypervisor Solutions in Virtual Private Server Benchmarking Test Conducted by Cloud Spectator

Virtuozzo Announcements

SEATTLE – Virtuozzo, a leading virtual infrastructure software provider, today announced the independent results of a virtualization benchmarking test conducted by Cloud Spectator, a leading cloud infrastructure performance analytics firm. The Cloud Spectator report, titled Virtualization and Containers: Comparing Linux Performance on VMs and OS Containers, found that Virtuozzo Containers can outperform other hypervisor-based solutions for Virtual Private Server (VPS) deployments.

For the test, Cloud Spectator observed differences in container and virtual machine performance when deployed on the same amount and type of hardware, and configured with identical load generator environments. Cloud Spectator ran performance tests for 24-hours to measure performance and performance stability of the virtual processor, memory bandwidth and disk IOPs. The benchmarks were run using Virtuozzo ContainersTM and two hypervisor-based solutions.

Key Findings

The Cloud Spectator test data shows that in the environments tested, the performance difference between containers and the hypervisor-based solutions can be significant when deploying virtual private servers – in some cases as high as 50%. Below are the report’s key findings:

  • Virtuozzo ContainersTM demonstrated the highest system performance observed in the study.
  • Virtuozzo ContainersTM scored higher in processor performance than the hypervisor-based VMs.
  • Virtuozzo ContainersTM showed similar performance stability with 2.4% variance.

“Our study looked at how an optimized container environment could perform compared to hypervisor-based virtual machines, and the results show us that containers can deliver performance advantages,” said Kenny Li, chief executive officer at Cloud Spectator.

“The Cloud Spectator study clearly shows that containers are a better choice than hypervisor-based solutions for virtual private server deployments, helping service providers get better performance and better profitability,” said Alex Kobets, chief technology officer at Virtuozzo. “Additionally, the tests show that the Virtuozzo Containers are much more resistant and elastic when it comes to dealing with load spikes, which is a critical requirement to help service providers deliver the best possible experience for end user customers.”
