I read here about the fees difference when paying to many addresses at once instead of doing it one after another. I was wondering whether this applies to the transaction time as well. Is it significantly faster if paying to N addresses at one? If so, could you please give an example, say N = 20.

For all transactions, "transaction time" is effectively 0. A transaction is created nearly instantaneously and broadcast to the network with no noticeable delay to a human.
What you are confirmed about are confirmation times. The time it takes to get a confirmation is only related to the transaction fee rate paid and the time it takes to mine a block. The size of the transaction is irrelevant.
Does this mean that given the same fee rate, a transaction to pay one address and another transaction to pay 20 addresses will take same amount of time to be confirmed and appear on blockchain? – Dark Templar – 2018-04-30T07:47:11.703
@DarkTemplar By the same fee rate, a transaction with greater weight will pay a higher total fee per individual transaction (but, 1 vs many) and may enjoy a benefit when it comes to a miner selecting transactions to include in a proposed block. Many small transactions paying in total a greater fee may not seem as attractive. This, of course, is speculation. – Willtech – 2018-04-30T09:14:33.317
I think that you mean "What you are concerned about..." – Willtech – 2018-04-30T09:14:59.333
That makes sense, thank you for clarification. In addition to that, can you give me a "rough" estimate on how longer will it take to transfer 1 to N versus 1 to 1 address. – Dark Templar – 2018-04-30T09:24:26.417
There is no such a "roguth estimate" because there is no difference. Even if there were, it would not be noticeable due to the large amount of time in between blocks. – Andrew Chow – 2018-04-30T15:06:16.093
