CPU and System Topology
Server Description
An x86_64 virtual server featuring high memory density and dedicated Intel Xeon cores for memory-bound general-purpose workloads.
Alibaba Cloud ecs.e3.xlarge is an x86_64 virtual server hosted on the KVM hypervisor, featuring 8 dedicated vCPUs and 64.0 GB of RAM. Powered by an Intel Xeon 8163 processor running at 2.5 GHz, this instance provides a high memory-to-vCPU ratio of 8.0 GB per core, though it lacks local storage and GPU accelerators. Performance benchmarks show a contrast between weak single-core execution, such as in single-threaded gzip compression, and average multi-core performance. Memory bandwidth remains average, with read speeds of 60.77 GB/sec for large blocks. Given these characteristics, the ecs.e3.xlarge offers qualitative cost efficiency for memory-intensive tasks that do not demand high single-threaded CPU performance. It is best suited for workloads like static web serving, Redis caching, and general-purpose applications with moderate compute requirements.
