Try the xfs_info command (ie. xfs_growfs -n). By default, mkfs will
use 1200 blocks, unless you have a very large filesystem.

The log size is not in there - these are log statistics.

The growfs man page -l option is a bit of wishful thinking - there is
no kernel code behind it as yet. You will need to re-mkfs with the -l
option, something like: "-lsize=12000b".

Less disk space - I'm pretty sure memory use and cpu use will remain
exactly the same. You can tradeoff memory with the logbufs/logbsize
options.
