What methods can be used to optimize memory usage in an application?

To optimize the use of RAM in Go applications, the following methods can be applied:

• Memory profiling with pprof to identify leaks and "heavy" sections.
• Using object pools (sync.Pool) for reusing frequently created structures and reducing garbage collector load.
• Minimizing allocations: avoid unnecessary copying, use pointers when justified.
• Data structure optimization: choose appropriate data types, pack struct fields to reduce padding.
• Explicit resource release: close files, connections, channels to free memory.

Example of using sync.Pool:

var bufPool = sync.Pool{
    New: func() interface{} {
        return make([]byte, 1024) // 1KB buffer
    },
}

func process() {
    buf := bufPool.Get().([]byte)
    defer bufPool.Put(buf)
    // use buf
}
