Pre-allocate Slices with Known Capacity When the eventual size of a slice is known, pre-allocating with make([]T, 0, capacity) creates the underlying array a single time. This critical practice avoids multiple, inefficient reallocations and the expensive process of copying all existing elements to a new, larger array as you append data.

Use the arena for Short-Lived Objects This is perfect for functions that create many temporary objects (like during a single request), as it can nearly eliminate GC pressure from that workload. or else you can also implement custom arena code. Custom Arena backed by mmap file function might help if you want storage for those value and gaurantees which comes with it if process fails or you need more space than allocated RAM size. If data persistence is not important, implementing arena with off-heap storage using unsafe package and pointers can be very beneficial as it is faster than GC heap (default) acce
