https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212681 --- Comment #57 from rainer@ultra-secure.de --- Well, I did do dd test, but they only write on a filesystem. It was (back then) most likely on ZFS, with compression etc. that changed t= he results. Esp. if I just write zeros from /dev/null. That's why I switched to dc3dd because it does the same thing on Linux and = on FreeBSD and completely eliminates the filesystem (and caching) layer as wel= l as any other kinds of write-optimization. I've now created an empty UFS filesystem on my 50G volume and run unixbench= on it. --=20 You are receiving this mail because: You are the assignee for the bug.=
