    CPU and System Topology

    Server Description

    A memory-intensive server combining massive RAM capacity and local SSD storage with strong uncached memory bandwidth for database workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure M128-64ms is an x86_64 memory-optimized server configured with 64 dedicated vCPUs from 32 physical Intel Xeon 8280L cores at 2.7 GHz. It features a massive 3892.0 GB of RAM, providing 60.81 GB of memory per core, alongside 4194 GB of local SSD storage. Benchmark results reveal a significant performance tradeoff: while uncached memory read and write bandwidth are strong, single-core CPU performance is poor. Multi-core CPU execution, Passmark database operations, and Redis SET throughput perform in the average tier. This hardware profile is qualitatively cost-efficient for memory-bound applications requiring vast RAM capacity, such as large in-memory databases and heavy data processing, but is inefficient for compute-heavy or single-threaded tasks.

    Workload Profiles

    1.9Score
    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.
