Well for one simple thing you set your "MAXFRAMES" to 7.
Set PACLEN to 255. That wont change your baud rate but providing
signals are good it will give you the max thruput on msg traffic.

Some experiments over an obstructed path on 70 cm,
9600 baud, suggest maxframe 16 - 32 and paclen of
60 -100 give the maximum throughput. Note that this
is an implementation of AX.25 that uses slow-start
and selective reject / out-of-order frame recovery.

Across a "very good" line of sight path, maxframe of
32 and paclen of 1024 did best.

These were point-to-point links, half duplex.
About 10 MB of data were used for the tests.
