the fastest board for TCP/IP WiFi communication

hi

I need to send data with TCP/IP protocol at the speed of at least 115 kbit per sec. What kind of board can i use?
Since i need most of the pins in the board, using a shield which uses some of the pins may not be a good option. so, i would prefer to use a board with embedded wifi. I tried Arduino uno wifi and arduino yun with no success in achieving that speed :frowning:

I would appreciate if you help me by sharing your experience.
thanks
