Your patch appeared to get stripped from the mailing list. I would
like to try your patch in MidnightBSD which is based on FreeBSD 6 if
you'd be willing to email it to me. :)

To: [EMAIL PROTECTED]
Hello Sean,
My name is Victor, I've sent you a patch which solved the bug in
which random(6) would
be way to slow to handle files that are greater than 10MB+, well, I am
re-sending you that
same patch with little modifications, do you think you could include
it in the src tree?
This patch also increases random(6) performance dramatically even
when working with small-to-medium file sizes, it should be a good
addition to the random(6) source tree, and
its also been extensivelly tested against all features of random(6)
and it scale really well with big files, for example:
--
[EMAIL PROTECTED] yes | head -20 test
[EMAIL PROTECTED] time ./random -f test /dev/null
0.257u 0.015s 0:00.27 96.2% 11+14460k 0+0io 0pf+0w
[EMAIL PROTECTED] time random -f test /dev/null
187.366u 0.007s 3:07.39 99.9% 10+12945k 0+0io 0pf+0w
--
And this was on a Intel Core Duo 2 1.8ghz with 1GB of RAM, with one
process taking
less than a second to randomize it all, and the other taking 3
minutes, I think its a good
patch to be applied on the source tree.
I also took the time to change the man page of random(6) to better
describe the changes,
basically removed the BUGS sections (since that bug is solved by the
patch) and included a new line on the HISTORY section describing my
contribution to the program :).
Attached are the patches for randomize_fd.c and random.6, also a
little description of the changes made in randomize_fd.c is in the
readme file.
Hope you find that this is patch is commitable, I would appreciate to
have contributed to FreeBSD even if its just this little contribution
:)
ciao,
victor loureiro lima
