What's that?

It is exactly eight times more which looks like a wrong block size
calculation. I use Perl's stat output and multiply blksize and blocks
fields, then dividy by 8. 

So either Perl is broken, or the filesystem driver is broken in the
kernel. Please try following:

perl -e '@a=stat "."; print "blocksize: $a[11]\n"'

and then compile the attached file with gcc and run it. Let me know how
the output looks like.

Regards,
Eduard.
