A little data never hurts. Even if the numbers mean little.

Strangely the openssl in Solaris 10 is SHA256 ignorant.
However one may use the mdigest in schilytools also :
$ ptime /opt/schily/bin/mdigest -a sha256 linux-3.5.1.tar.bz2

Regardless .. let's do a test here :
$ mkdir foo
$ cd foo
$ ptime /opt/schily/bin/star -x -bz -xdir -xdot -U -fs=64m -fifostats -time file=../linux-3.5.1.tar.bz2
