CPIO buffer size choice?

CPIO buffer size choice?

Post by Pat Malo » Tue, 05 Nov 1996 04:00:00



We have been experimenting with different buffer sizes on the cpio
command (-Cxxxxx) in an attempt to improve backup throughput.

Aside from the obvious trial/error method, is there some way to
determine what the most efficient buffer size is?

(This is i/o going to 8mm exabyte drives, some of it is large db files,
some is smaller user/system files)

Any comments would be appreciated.
