Pete-

Thanks for the reply.  My application program is doing what you suggest; the
input buffer is about 125k bytes and does a single read() to fill it. When the
read() command returns, the program does a single write().  But this simple
read() - write() loop takes several times longer to copy a file than when I use
OS9's copy, with -b=64K  (or larger).  I hoped perhaps there way to specify
this option in C.

You say the buffer is actually a driver buffer.  Is there a way to modify the
driver to get it to use a larger buffer?

Thanks again,

Bill
