      CPU and System Topology

      Server Description

      A balanced 32 vCPU and 128 GB RAM instance providing steady multi-threaded execution for web backends and general enterprise workloads.

      General Purpose

      Alibaba Cloud ecs.sn2.7xlarge is a general-purpose instance featuring 32 dedicated vCPUs (16 physical cores on an Intel Xeon 8163 processor at 2.5 GHz) and 128 GB of RAM. Operating under the KVM hypervisor, it provides a 1:4 vCPU-to-RAM ratio, 33 MB of L3 cache, and support for AVX-512F instructions. Network performance is rated at a 6 Gbps baseline, with no local storage or GPUs included. Benchmark results demonstrate weak single-threaded performance in gzip compression and single-core synthetic tests, but reliable middle-tier throughput in multi-core tasks, including PassMark CPU testing, Clang software compilation, and multi-threaded bzip3 decompression. The server delivers average performance for Redis operations, database tasks, static web serving, and medium-scale LLM prompt processing. This resource profile offers balanced cost efficiency for multi-threaded general-purpose compute, web application backends, and containerized enterprise services.

      Workload Profiles

      0.94Score
      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.
