Answer 1

For the second time you ask a non-specific question, which is difficult to fully answer.
Since you do not provide any details (server settings, type of passing traffic, average packet size, etc.), I would venture to suggest that there is more data transmitted due to the fact that vpn basically adds a certain amount of data to each packet (see eg here ) and in the case of passing a large number of small packets, the overhead can be significant.
