CPU and System Topology
Server Description
A dedicated 16-core Intel Xeon compute-optimized instance designed for balanced processing workloads, web serving, and database operations.
Alibaba Cloud ecs.u1-c1m2.4xlarge is an x86_64 compute-optimized instance featuring 16 dedicated Intel Xeon physical cores operating at 2.5 GHz and 32.0 GB of RAM. Running on the KVM hypervisor, this server provides a 1:2 core-to-memory ratio, a 33 MB L3 cache, and a baseline network bandwidth of 5 Gbps, with no local storage or GPU accelerators included. Benchmark results indicate steady mid-range performance, with a PassMark CPU score of 19226.97 and a Redis SET throughput of 15.82 million operations per second. The instance is qualitatively cost-efficient for compute-heavy tasks that do not demand high memory density. It is best suited for web serving, database operations, and moderate computational workloads such as lightweight LLM inference.
