Until everyone gets the updated "mount" package,
/usr/src/linux/Documentation/filesystems/xfs.txt is a good place to
look:
biosize=size
Sets the preferred buffered I/O size (default size is 64K).
"size" must be expressed as the logarithm (base2) of the
desired I/O size.
Valid values for this option are 14 through 16, inclusive
(i.e. 16K, 32K, and 64K bytes). On machines with a 4K
pagesize, 13 (8K bytes) is also a valid size.
The preferred buffered I/O size can also be altered on an
individual file basis using the ioctl(2) system call.
