 ## Azure Cobalt 100 Arm-based processor
 
-Azure Cobalt 100 is Microsoft’s first-generation, in-house Arm-based processor built on Arm Neoverse N2. It is a 64-bit CPU that targets cloud-native, scale-out Linux workloads such as web and application servers, data analytics, open-source databases, and caching, delivering strong performance and energy efficiency. Running at 3.4 GHz, Cobalt 100 allocates a dedicated physical core for each vCPU to provide consistent, predictable performance.
+Azure Cobalt 100 is Microsoft's first-generation, custom-designed Arm-based processor built on the advanced Arm Neoverse N2 architecture. This high-performance 64-bit CPU is specifically optimized for cloud-native, scale-out Linux workloads including web servers, application servers, real-time data analytics, open-source databases, and in-memory caching solutions.
+
+Key performance features include:
+- Clock speed: 3.4 GHz for optimal processing power
+- Core allocation: dedicated physical core per vCPU for consistent performance
+- Architecture: Arm Neoverse N2 for superior energy efficiency
+- Target workloads: cloud-native applications and microservices

+## Metrics explained
 
-- ns/op: nanoseconds per operation (lower is better)  
-- B/op: bytes allocated per operation (lower is better)  
-- allocs/op: number of heap allocations per operation (lower is better)
+The metrics reported by go test -bench include ns/op, which measures nanoseconds per operation and reflects latency where lower values are better, B/op, which shows the number of bytes allocated per operation and helps identify memory efficiency, and allocs/op, which indicates the number of heap allocations per operation and highlights how often memory is being allocated, with lower values preferred in all cases.
