Hi Matthias,
The code from TI has been getting slower, but I haven't investigated the
reason. Big speedups are in the pipeline, though. Using GDB6.0 speeds
things up a lot, as it does reasonable sized writes. The current GDB
5.1.1 sometimes does reasonable sized write (300+ bytes per chunk), but
keeps switching to tiny chunks (30 odd bytes) for no obvious reason.
Buffering in gdbproxy is also in progress (when I get time!)
Regards,
Steve

I have done some tests, and obviously newer version of gdbproxy

The oldest (and largest) version is the fastest one. This is quite independent
from the --debug flag. Steve, any idea what's wrong?
