To my knowledge, increasing the size of pipe and fifo (named pipe) buffers requires tweaking a header file and recompiling the kernel. The parameter in question is PIPE_BUF.
If you're using a recent linux, it's probably 64K. On an older linux, I believe it's 4K. On some other UNIX systems, it may be as low as 512 bytes (I believe this is the minimum allowed by POSIX).
You should be able to check the value with getconf PIPE_BUF pathname, where "pathname" is the path to the named pipe or the directory in which the named pipe will be located.

I did
cat < myFile >> myPipe
I was hoping that if I did ls -l, myPipe would now be holding the contents of myFile, and would be the same size. But it was 0.
Also strange was that when I did the command above, cat did not return control back to the shell. Why?
