I have a question about about the overhead of VPN while torrenting.
I use private trackers and before VPN my ISP reported download usage in GB was always 10 to 15% higher than my torrent client reported download amount. This is when all other internet usage is off so torrenting is isolated. I know this is normal as there is tracker reporting, retransmissions, etc going on in the background in any normal torrent download.
However since using VPN this overhead has jumped to 33 to 38% in the same isolated torrenting circumstances. Can anybody confirm if this is normal for torrenting on with a VPN.
