Maximum Segment Size

Enabling Nagle's algorithm should do this: Nagle's attempts to limit the number of small segments on a network by buffering data until it receives the previous ACK.

 

 

That being said, I have also seen Nagle's add noticeable latency to an application precisely because it is delaying sending data. According to the Wikipedia article on Nagle's (Click here) it sometimes interacts badly with Delayed ACKs. I have not tried disabling those with Nagle's enabled though.

 

 

Also, I would create a new profile and leave the built-in tcp one at the default settings.
