Reduce lock contention and garbage collection overhead in Go by using sync.Mutex for critical sections and sync.Pool for object reuse.

Optimize concurrent Go programs by minimizing lock contention, using sync.Mutex for critical sections, and leveraging sync.Pool for object reuse to reduce garbage collection pressure.

var pool = sync.Pool{
    New: func() interface{} {
        return &Buffer{}
    },
}

func process() {
    buf := pool.Get().(*Buffer)
    defer pool.Put(buf)
    // Use buf
}
