Go provides several built-in tools and techniques for performance tuning and optimization. 
Here are some of them:
Profiling: Go provides a built-in profiler that can be used to identify performance bottlenecks in your code. The profiler can be enabled by adding the -cpuprofile flag to your Go program, which will generate a CPU profile that can be visualized using various tools.
Concurrency: Go's lightweight threads (goroutines) and channels make it easy to write concurrent programs that can take advantage of multiple CPU cores. By using goroutines and channels, you can parallelize your code and improve performance.
Garbage collection: Go has a concurrent garbage collector that automatically manages memory allocation and deallocation. This means you don't have to worry about manual memory management, and your program's memory usage will be optimized automatically.
Memory pooling: Go's standard library provides a sync.Pool type that can be used to implement memory pooling. Memory pooling can be used to reduce the overhead of allocating and deallocating memory, which can improve performance.
Benchmarking: Go provides a built-in benchmarking tool that can be used to measure the performance of your code. By writing benchmarks for your code, you can identify performance bottlenecks and track performance improvements over time.
Some best practices for performance tuning in Go include:
Use channels and goroutines to parallelize your code and take advantage of multiple CPU cores.
Minimize allocations by reusing memory wherever possible. Use sync.Pool to implement memory pooling.
Avoid unnecessary memory copies by using pointers and slices instead of copying large data structures.
Use the built-in profiling and benchmarking tools to identify performance bottlenecks and track performance improvements over time.
Use the -race flag to detect data races in your code, which can cause performance issues and other problems.
