I'm using Ubuntu i386. I just thought that since MySQL talks blithely 
about packet sizes of 16mb I would investigate how my protocol interface 
performs with large buffers and large BLOBS.

I believe Ubuntu imposes the buffer size limitation and you have to mess 
with kernel configuration files to change that. But I don't want to go 
there and wondered if I was missing some simple point.
