:One question that probably interests many of us is, can tuning those

:size, or does the number of inodes and/or cylinder groups affect it?

Yes. Increasing the number of bytes per inode will reduce the number
of inodes and thus reduce fsck time. Increasing the number of cylinders
in a group will localize inodes into bigger chunks, reducing seeking
and also thus reduce fsck time.
