CPU and System Topology
Server Description
A memory-optimized virtual server featuring high RAM density and dedicated Intel Xeon processors for memory-bound workloads without local storage.
Alibaba Cloud ecs.r6.2xlarge is a memory-optimized instance featuring 8 dedicated vCPUs and 64.0 GB of RAM, powered by an Intel Xeon 8269CY processor running at 2.5 GHz. Built on the x86_64 architecture and KVM hypervisor, it offers a high memory-to-vCPU ratio of 8.0 GB per core but lacks local storage and GPU acceleration. Baseline network bandwidth is rated at 2 Gbps. Performance benchmarks reveal a contrast between weak single-core execution and average multi-core and memory performance. The instance achieves average results in Passmark memory tests, Redis SET operations at 6.84 million operations per second, and static web serving at 6.52 GB/sec. This profile makes the instance suitable for memory-intensive workloads like database operations, in-memory caching, and text processing where high memory density is prioritized over raw single-threaded compute power.
