      CPU and System Topology

      Server Description

      A balanced x86_64 compute instance featuring dedicated Intel Xeon processors and 48 GB of RAM for general-purpose workloads.

      General Purpose

      Alibaba Cloud ecs.cm4.3xlarge is a general-purpose x86_64 server instance featuring 12 dedicated Intel Xeon 8369HB physical cores running at 3.2 GHz, paired with 48.0 GB of RAM. Operating on the KVM hypervisor, this instance lacks local storage and GPU accelerators, relying on a 4 Gbps baseline network bandwidth. Performance benchmarks generally fall into the average tier, with a Passmark CPU score of 13441.38 and a Redis SET throughput of 11.64 million operations per second. However, memory performance and physics simulations show relative weakness. The instance is best suited for balanced workloads such as static web serving, database operations, and general-purpose applications that do not require high-density local storage or intensive machine learning capabilities.

      Workload Profiles

      0.712Score
      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.
