Benchmarking Go code requires executing built-in testing tools like `go test -bench=. -benchmem` to measure memory allocations and identify latency bottlenecks. This process captures baseline metrics for optimizing hot paths.

High latency under load in Go applications is typically caused by unresolved hot paths and excessive memory allocations. Profiling CPU usage and benchmarking targeted code sections identify these specific performance bottlenecks for resolution.

Profiling Go applications for performance optimization is best achieved by using Go's built-in CPU profiling tools. This approach analyzes execution to pinpoint hot paths, guiding targeted reductions in memory allocations and latency.

Reducing memory allocations in a Go service involves identifying allocation hot spots through benchmarking with `-benchmem`. Applying targeted optimization techniques to these specific code paths minimizes heap allocations and improves latency.

Benchmark tests are required to optimize Go performance effectively. Executing benchmark tests and CPU profiling provides the necessary data to identify hot paths, measure allocations, and apply targeted optimizations accurately.
