      Server Description

      A dedicated 16-core compute-focused server with a 1:2 memory-to-CPU ratio, optimized for parallelized workloads and multi-threaded applications.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.n1.3xlarge is an x86_64 server featuring 16 dedicated Intel Xeon 8163 vCPUs running at 2.5 GHz, paired with 32.0 GB of RAM and no local storage. Built on the KVM hypervisor, this instance provides a 1:2 vCPU-to-RAM ratio. Benchmarks show weak single-core CPU and memory performance, but average multi-core capabilities, making it a viable option for parallelized workloads. With average multi-core Geekbench and Passmark scores, alongside a static web serving throughput of 10.26 GB/sec, this server is suited for multi-threaded tasks, software compilation, and web serving. It represents a compute-focused profile where raw core count is prioritized over high per-core memory allocation or local storage.

      Workload Profiles

      0.789Score
      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.
