How to minimize I/O while sending files

[watn3y]

How would I go about minimizing I/O when uploading a file? I.e. send/upload as little data as possible.

would

sendByCopy := tgbotapi.NewCopyMessage(chatID, fromChatID, messageID)
bot.CopyMessage(sendByCopy)

or

sendByFileID:= tgbotapi.NewDocument(chatID, tgbotapi.FileID(fileID))
bot.Send(sendByFileID)

be most efficient?

Either of those would be pretty similar in terms of reducing I/O for the bot (both are sending fairly small requests with some kind of ID), I don't think there's any way to use less resources to upload an existing file.
