Has anyone done any benchmarking work on ccd interleaves to determine
which ones are better and worse? I notice that the ccdconfig manual
page gives 16 as an example interleave, but I've found that powers
of two tend to concentrate inode activity on one drive (I've seen
cases where I untar a file and one drive in the ccd is quite active
while the other is virtually idle). I've been using 96, (which is
about 20% faster than 32 when untarring a large directory tree with
a lot of small files in it), but haven't really done a lot of
experimentation yet to see if perhaps prime interleaves or something
like that would be more optimal.
