The SILO buffer is the serial line buffer.  The 030-25 should be able
to keep up, you just have to have a properly configured kernel.

Set these options and recompile:

# These options improve performance with the built-in serial port
# on slower Amigas.  Try the larger buffers first then lev6_defer.
options         "SERIBUF_SIZE=8192"
options         "SEROBUF_SIZE=64"
options LEV6_DEFER      # defers l6 to l4 (below serial l5)
