Principled Technologies (PT) testing showed vSphere Kubernetes Service sustained more throughput and lower latency for a Kafka workload without adding overhead.
PALO ALTO, CA, UNITED STATES, January 7, 2026 /EINPresswire.com/ — A new hands-on study from Principled Technologies (PT) demonstrates that virtualized Kubernetes deployments using VMware vSphere Kubernetes Service (VKS) with VMware Cloud Foundation (VCF) can deliver substantially better performance than a bare-metal Red Hat OpenShift Container Platform (OCP) solution for both modern streaming and traditional OLTP workloads.
The study compared identical four-node Dell PowerEdge R640 clusters, configured with either VKS on VCF or OCP on bare metal, running two real-world workloads: an Apache Kafka producer benchmark workload and an online transaction processing (OLTP) workload on PostgreSQL. According to the report, the VKS configuration achieved up to 73 percent greater throughput and up to 78 percent lower latency for the Kafka workload versus the OCP solution on bare metal. In OLTP testing, the VKS deployment supported 80 percent more new orders per minute (NOPM) and reduced latency by 72 percent compared to the bare-metal OCP deployment. Organizations evaluating Kubernetes platforms for streaming analytics or high-throughput transactional databases may find these results useful when looking for a solution that balances performance, operational flexibility, and infrastructure consolidation.
The report states that “for enterprises that depend on rapid ingestion, such as those in retail, logistics, and fintech, higher throughput can mean systems process more data in less time.” The report also notes regarding latency that “faster response times help ensure that fraud detection engines remain accurate, supply chain systems stay synchronized, and user-facing applications provide timely updates.” In addition to the higher throughput and lower latency delivered by VKS, the virtualized solution supported more workloads than the OCP deployment on bare metal before exceeding a potentially problematic latency threshold of 50 milliseconds.
Organizations running more traditional SQL database workloads should note of the OLTP findings that “when your database can process more transactions in the same amount of time, your customers and staff get a more responsive experience, critical for engagement and productivity.”
