      CPU and System Topology

      Server Description

      An x86_64 virtual server with a high memory-to-vCPU ratio, optimized for database caching and general-purpose enterprise workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.u1-c1m8.2xlarge is an x86_64 virtual machine instance featuring 8 dedicated Intel Xeon vCPUs (4 physical cores) running at 2.5 GHz and 64.0 GB of RAM. Operating on a KVM hypervisor, it provides a high memory-to-core ratio of 8.0 GB per vCPU but lacks local storage and GPU acceleration. Benchmark results place the instance in the average tier for general compute, memory bandwidth, and database operations, as evidenced by a Passmark CPU score of 10405.69 and 7.81 million Redis SET operations per second. However, it exhibits poor performance on larger workloads like 7B LLM inference. This memory-optimized profile is highly cost-efficient for workloads requiring substantial memory capacity without high-performance storage, making it well-suited for in-memory databases, caching layers, web serving, and general-purpose enterprise applications.

      Workload Profiles

      0.52Score
      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.
