      Server Description

      A compute-optimized ARMv9 instance with dedicated physical cores and balanced memory bandwidth for lightweight, parallelizable microservices and web serving.

      Compute Optimized

      Amazon Web Services c8gb.xlarge is a compute-optimized instance featuring 4 dedicated physical cores powered by an ARMv9 AWS Graviton Neoverse-V2 processor running at 2.8 GHz. Built on the Nitro hypervisor, this arm64 instance includes 8.0 GB of system memory, providing a 2.0 GB per core ratio, and offers an 8 Gbps baseline network bandwidth without local storage or GPU accelerators. Performance benchmarks indicate average capabilities across standard compute, memory bandwidth, and web serving tasks, with a notable strength in single-threaded bzip3 decompression. However, it exhibits weaker performance in Passmark CPU tests and cryptographic operations. The c8gb.xlarge is suited for lightweight compute-bound workloads, static web serving, and Redis operations that benefit from dedicated physical cores, offering a cost-efficient ARM-based resource profile for parallelizable microservices.

      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.
