      CPU and System Topology

      Server Description

      An entry-level, dedicated dual-core virtual server designed for lightweight single-threaded applications and basic development environments.

      General Purpose

      Alibaba Cloud ecs.u1-c1m4.large is a general-purpose virtual instance featuring 2 dedicated Intel Xeon physical cores running at 2.5 GHz on an x86_64 architecture. It is equipped with 8.0 GB of RAM, providing 4.0 GB per core, but lacks local storage and GPU acceleration, relying on a 1 Gbps baseline network interface. Benchmark data shows average single-core performance, supported by AVX and AVX512F instruction sets, but poor multi-core scaling and memory bandwidth, both ranking in the bottom 10% of tested servers. Consequently, this instance represents a budget-friendly option for low-intensity, single-threaded workloads. It is best suited for lightweight web serving, basic application hosting, and development environments where high parallel processing and memory throughput are not critical.

      Workload Profiles

      0.174Score
      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.
