CPU and System Topology
Server Description
A memory-optimized virtual server featuring a high memory-to-core ratio, tailored for caching, databases, and moderate compute workloads.
Alibaba Cloud ecs.e4.2xlarge is a memory-optimized virtual server featuring 8 vCPUs and 64.0 GB of RAM, running on an Intel Xeon E5-2682 v4 processor at 2.5 GHz. Utilizing the KVM hypervisor on an x86_64 architecture, this instance provides a high 8.0 GB of memory per core with a shared CPU allocation. It lacks local storage and dedicated GPUs, relying on a 1 Gbps baseline network. Benchmarks indicate average multi-core and memory bandwidth performance, contrasted by weak single-core processing and compression speeds. The instance excels in memory-bound scenarios, showing strong Redis SET throughput of 9.13 million operations per second and static web serving at 8.41 GB/sec. It is highly suitable for memory-intensive, compute-moderate workloads such as caching, database hosting, and web serving.
