      CPU and System Topology

      Server Description

      A dedicated 48-vCPU compute-optimized platform featuring high-frequency Intel Xeon processors and strong multi-threaded performance for demanding CPU-bound applications.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfc7.12xlarge is a compute-optimized instance featuring 48 dedicated vCPUs and 96.0 GB of RAM, powered by an Intel Xeon 8369HB processor running at 3.3 GHz. Built on the x86_64 architecture with a KVM hypervisor, it allocates 2.0 GB of memory per core and includes a 33 MB L3 cache alongside AVX-512 instruction support. The instance lacks local storage and GPUs, relying on a 16 Gbps baseline network bandwidth. Performance benchmarks show strong multi-threaded capabilities, highlighted by a bzip3 decompression rate of 206.84 GB/sec and a Passmark memory score in the top 25%. It delivers stable mid-tier performance across Redis operations, static web serving, and medium LLM inference. This configuration is highly suitable for compute-heavy workloads, software compilation, and web serving applications that do not require local storage.

      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.
