...but with much bigger blocksizes, and with a netcat-like ability to use sockets.
The program is at http://dcs.nac.uci.edu/~strombrg/pnetcat I'm a bit concerned about the program's performance, because it actually seems to get slower sometimes with larger blocksizes, which really isn't what I'd been expecting. Also the megabits/second I'm getting isn't really stellar either, at least not when using it on an optical network (fibre and optical switching). Also, is there any way to make len(big_buffer) fast, or to speed up or eliminate the string slicing required (?) to handle partial writes? Thanks a bunch! (I'll put up a descriptive web page on the program later, when I have a little bit more time. But for now, you can get a usage message with the -h flag) -- http://mail.python.org/mailman/listinfo/python-list
