      CPU and System Topology

      Server Description

      A memory-optimized virtual server with dedicated Intel Xeon processors and high memory bandwidth for demanding database and caching workloads.

      Memory OptimizedStorage & Database

      Microsoft Azure M64bs_v3 is a memory-optimized server from the MBSMediumMemoryv3 family, featuring 64 dedicated vCPUs and 512.0 GB of RAM. Powered by an Intel Xeon 8473C processor at 4.0 GHz, it operates on the x86_64 architecture under Hyper-V. The instance lacks local storage but is optimized for Premium Block Storage. It delivers strong memory bandwidth, reaching 216.83 GB/sec for large block reads, and excels in database operations with 71.51 million Redis SET operations per second. It is designed for memory-heavy workloads like databases and in-memory caches.

      Workload Profiles

      3.4Score
      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.
