      Server Description

      An arm64 virtual server featuring high memory density and dedicated CPU cores for database and memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r8y.2xlarge is an arm64-based, memory-optimized virtual server powered by an 8-core Alibaba Yitian YiTian710 processor running at 2.75 GHz. It features 64.0 GB of RAM, providing a high 8.0 GB per core ratio, but includes no local storage and relies on a 5 Gbps baseline network. Performance benchmarks generally fall into the average tier, with a PassMark CPU score of 6807.57 and a Redis SET throughput of 12.61 million operations per second. However, cryptographic performance is a notable bottleneck, scoring in the weak tier on PassMark encryption tests. Large-scale LLM inference is also limited, with poor throughput on 7B parameter models. This instance is best suited for memory-intensive workloads such as database operations, caching layers, static web serving, and general arm64 application hosting where local storage is not required.

      Workload Profiles

      0.71Score
      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.
