I'm trying to reuse the same CURL handle in order to reuse it's connections associated with it. However, I noticed a huge performance drop when I constantly change the Ip address of my request. When I keep the IP address unchanged everything is fine,
TCP sockets are "bound" to a the source IP when you create them. When you change IP, you efffectively ruins the connections setup to the former IP address and I suspect it takes a moment for curl to realize, tear down the old connection and create a new one. Over and over.
I don't see how that can be fixed with TCP. With QUIC, things can be done better.
