Comparison numbers are only valid of the tests run are the same. 

So here is the UFS test once more without the compression and
with -no-fifo : 

jupiter-sparc-SunOS5.10 # ptime /opt/schily/bin/star -x -xdir -xdot -no-fifo -U file=../linux-3.5.1.tar
star: 46849 blocks + 0 bytes (total of 479733760 bytes = 468490.00k).

real    27:44.237
user        2.031
sys        42.419

Not a good result.
