What methods can be used to increase the speed of data read operations?

To increase data read operation speed in Go, several approaches can be used:

• Buffering: use buffered reads with bufio.Reader, which reduces the number of system calls.

• Parallel reading: if data can be read in parallel (for example, from multiple files or parts of a file), use goroutines for parallel processing.

• Data format optimization: use faster serialization formats or binary formats instead of text.

• Using efficient data structures: for example, reading into pre-allocated slices or structures to avoid unnecessary allocations.

Example of using buffered reading:

file, _ := os.Open("data.txt")
reader := bufio.NewReader(file)
line, err := reader.ReadString('\n')
