Howdy,

I believe it's time for us to upgrade our sysctl values for TCP sockets so that
they are more in line with the modern world.  At the moment we have these limits on
our buffering:

kern.ipc.maxsockbuf: 262144
net.inet.tcp.recvbuf_max: 262144
net.inet.tcp.sendbuf_max: 262144

I believe it's time to up these values to something that's in line with higher speed
local networks, such as 10G.  Perhaps it's time to move these to 2MB instead of 256K.

Thoughts?

Best,
George
