Is your feature request related to a problem? Please describe.

Ability to set sndbuf + rcvbuf as well as push them to the client. This is extremely important for mitigating bandwidth bottlenecks, especially on faster and/or higher latency links.

Describe the solution you like

An option for each with a text box where the value can be entered in bytes. Either 2 boxes (with an accompanying checkbox to push the custom value for server instance), or separate boxes (4 for server instance, 2 for client instance). Essentially achieve an affect similar to:

Server:

sndbuf 2097152
push "sndbuf 2097152"
rcvbuf 2097152
push "rcvbuf 2097152"

Client:

sndbuf 2097152
rcvbuf 2097152

Describe alternatives you considered

There are no alternatives for this.
