Server Description
An x86_64 compute-focused instance with a 1:1 vCPU-to-RAM ratio, designed for lightweight multi-threaded workloads without high memory demands.
Alibaba Cloud ecs.u1-c1m1.2xlarge is an x86_64 compute-focused server instance featuring 8 dedicated vCPUs and 8.0 GB of system memory. Powered by an Intel Xeon processor running at 2.5 GHz, it provides a 1:1 memory-to-vCPU ratio, making it a cost-efficient option for compute-bound workloads with low memory requirements. The instance lacks local storage and GPU accelerators, relying on a 2 Gbps baseline network bandwidth. Benchmark data indicates average performance across standard CPU and memory tests, with a stress-ng multi-core score of 7723.84 and a static web serving throughput of 9.4 GB/sec. However, it exhibits weak performance on larger workloads, such as LLM inference on 7B models. It is best suited for lightweight web serving, software compilation, and basic multi-threaded processing tasks.
