      Server Description

      A dedicated dual-vCPU compute instance designed for lightweight single-threaded workloads requiring consistent CPU allocation without local storage.

      Compute Optimized

      Amazon Web Services c4.large is a compute-optimized instance featuring 2 dedicated vCPUs and 1 physical core powered by an Intel Xeon E5-2666 v3 processor running at 2.9 GHz. It is configured with 4.0 GB of RAM, providing 1.88 GB per core, and operates on the Xen hypervisor without local storage or GPU accelerators. Network performance is anchored at a baseline of 1 Gbps. Benchmark data shows average single-core performance in stress-ng and gzip compression, though multi-core and memory bandwidth results are generally constrained. This instance offers an entry-level dedicated compute profile, making it suitable for lightweight single-threaded applications, basic web serving, and utility workloads that require dedicated CPU allocation without the overhead of high memory or storage demands.

      Workload Profiles

      0.126Score
      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.
