    Server Description

    A memory-balanced virtual machine featuring dedicated Intel cores and substantial local storage for caching and lightweight database workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure L4s is an x86_64 virtual machine from the LS family, powered by an Intel Xeon 8370C processor running at 2.8 GHz with 4 dedicated vCPUs and 4 physical cores. It features 32.0 GB of RAM (8.0 GB per core) and 694 GB of Premium Storage capable local storage, with no GPU. Benchmarks indicate average performance in large-block memory bandwidth (50.82 GB/sec read) and Redis SET operations (6.03 million operations/sec), but weaker results in CPU-intensive tasks, with stress-ng single-core and multi-core performance falling into the bottom 10% and 25% respectively. This resource profile offers qualitative cost efficiency for memory-centric and storage-cached workloads that do not require heavy compute. It is best suited for caching layers, lightweight databases, Redis deployments, and moderate text or image processing.

    Workload Profiles

    0.389Score
    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.
