      CPU and System Topology

      Server Description

      A budget-friendly virtual server with shared Intel Xeon processors and local NVMe storage for lightweight development and testing workloads.

      Burstable & BudgetGeneral Purpose

      Hetzner Cloud cx23 is an entry-level virtual server built on the x86_64 architecture using the QEMU hypervisor. It features 2 shared Intel Xeon vCPUs running at 2.0 GHz, 4.0 GB of RAM, and 40 GB of local NVMe SSD storage. Benchmark results place this server in the lower performance tiers, with stress-ng single-core and multi-core CPU scores falling in the bottom 10%. Memory bandwidth is also limited, with large block write speeds at 16.93 GB/sec. Due to its shared CPU allocation and modest hardware profile, the cx23 is a cost-effective option designed for lightweight workloads. It is best suited for basic web serving, development environments, and small-scale testing where high-performance compute is not required.

      Workload Profiles

      0.15Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
