UFS on zvol: volblocksize and maxcontig
...figure out how it interacts with UFS. When the zvol was setup, I took
the default 8k size. Since UFS uses an 8k blocksize, this seemed to be a
reasonable choice. I''ve been thinking more about it lately, and have
also read that UFS will do R/W in bigger than 8k blocks when it can, up
to maxcontig (default of 16, ie 128k).
This presented me with several questions: Would a volblocksize of 128k
and maxcontig 16 provide better UFS performance? Overall, or only in
certain situations (ie only for sequential IO)? Would increasing the
maxcontig beyond 16 make any difference (good, bad or indiff...
