With faster networks like GigE having a larger packet size for 9p might have benefits. We have a small test plan9 network that uses a max packet size of 30*1024 rather than the default 8192.

To increase the size of 9p packets in the fileserver kernel
requires a simple patch to

Increasing the size of 9p packets in the cpu/terminal kernel
requires a simple patches to the files
