    CPU and System Topology

    Server Description

    A budget-friendly, single-core virtual machine with dedicated Intel Xeon processing and local storage for lightweight, single-threaded utility workloads.

    Compute OptimizedGeneral Purpose

    Microsoft Azure F1s is an entry-level, x86_64 virtual machine within the FS family, utilizing a single dedicated vCPU from an Intel Xeon 8272CL processor clocked at 2.6 GHz. It is configured with 2.0 GB of system memory, 4 GB of local storage, and runs on the Microsoft Hyper-V hypervisor. Lacking hyperthreading, its single-core and multi-core stress-ng benchmarks align at 1218.79, indicating limited processing capacity. Memory performance is constrained, with uncached large-block read bandwidth at 11.47 GB/sec and a PassMark memory score of 806.29. While it supports advanced instruction sets like AVX-512 and AES, its resource constraints make it highly specialized. This server is qualitatively cost-effective for low-intensity, single-threaded operations, basic static web serving, and small-scale development or testing workloads rather than resource-heavy database or multi-threaded applications.

    Workload Profiles

    0.11Score
    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.
