| Hi Sun Gurus,
How can I find out the max I/O size on a sun solaris system (5.8 and 5.9) -
meaning in a single I/O operation how many bytes are written to the disk or
read from disk.
Thanks for your help and time in advance!
TG
P.S. I am posting this question to both this ng and comp.unix.solaris since
I didn't response to a earlier post.

It's the "maxphys" kernel parameter; it defaults to 128K.
