      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring dedicated Intel Xeon processors, high RAM-to-vCPU density, and strong single-threaded performance.

      Memory OptimizedGeneral Purpose

      Google Cloud Platform c4-highmem-4 is a memory-optimized instance configured with 4 dedicated vCPUs and 31.0 GB of RAM, running on an Intel Xeon 8581C processor at 2.3 GHz. Utilizing the x86_64 architecture, it features 2 physical cores with hyper-threading and a 260 MB L3 cache, but lacks local storage and GPU accelerators. Benchmarks indicate top-tier single-core performance, particularly in text processing and single-threaded compression, though multi-core scaling and memory bandwidth remain relatively weak. Qualitatively, this instance provides a cost-effective entry point for memory-intensive workloads that do not require massive parallel compute power. It is well-suited for single-threaded applications, text processing, lightweight database operations, and small-scale LLM inference.

      Workload Profiles

      0.44Score
      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.
