My question regarding the 2 extremely major flaws in FreeBSD are being
addressed as I have learned from mature FreeBSD developers, due to my
question. Therefore many linux-fanatics who are focussed on an only-linux
world will no longer be able to use this issue.

These two stop-gap items will be at the forefront of the work for the next
year, along with a major move to start removing the BGL (Big Giant Lock,
also known as the MP lock) from code inherited from 4.x

...that is the one mentioned on dragonfly page too


Regarding the people who e-mailed me regarding mySQL on FreeBSD just Google
it:
http://www.google.com/search?hl=en&lr=&ie=UTF-8&q=performance+freebsd+mysql
..as you can see there are issues but they are being solved.


Furthermore...

This age actually tells me that my assertions are true regarding freeBSD's
problems:

http://www.freebsd.org/doc/en_US.ISO8859-1/articles/5-roadmap/article.html

This page also explains to me that these problems will be completely fixed
and that once FreeBSD 5.x is completely finished and stable that It will be
the best choice in operating systems.

I knew I wasn't trolling, but too many people sent me horrible hatred
messages.

Furthermore: HawkinsOS is a modified FreeBSD 5.x that retains the BSD
license and continues to give credit to the FreeBSD group, as well as once
this project is started will donate to the organization... So why would so
many people from so many lists say I'm doing illegal licesing things, etc.?
It also retains complete compatibilty to FreeBSD, which I've made sure to
help the FreeBSD project, as this is one issue where linux has been
successful.

I'm a FreeBSD fan and I always will be and I'm glade this issues are being
taken care of and I understand the money wasn't there like it was for Linux.
Please do not get the idea that I was trying to harass and troll.

I'm certainly glade we got that all taken care of.
