Yes, the server will slow down *just this client* instead of all traffic. Now, how does the server know which client to slow down? Because packets destined to this client are lost! This is perfectly okay. TCP will notice, retransmit the packet, and adjust the transmit speed until no packets are lost anymore. Losing those packets enable TCP to autodetect the maximum transmit speed - this is also how the internet works. With the server on gigabit and flow control disabled, you can have ten clients receiving 100Mb/s *each*. Forcing the server to 100Mb... Well, a bit less.
