    Server Description

    An entry-level, dedicated-core compute instance with balanced cache performance for light database operations and caching workloads.

    Compute OptimizedGeneral Purpose

    Microsoft Azure F4s is an x86_64 compute-optimized instance from the FS family, featuring 4 dedicated vCPUs on an Intel Xeon E5-2673 v4 processor clocked at 2.3 GHz. It is configured with 8.0 GB of RAM and 16 GB of Premium Storage-capable local storage, running on Microsoft Hyper-V. Benchmark results place its raw compute performance in the lower tiers, with stress-ng single-core and multi-core scores in the bottom 10% and 25% respectively. However, it maintains average performance in memory bandwidth for small cached blocks and Redis SET operations. This instance presents an entry-level, dedicated-core option for workloads with low memory requirements, making it suitable for light database operations, basic web serving, and caching.

    Workload Profiles

    0.339Score
    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.
