Hi John-Paul, Reread my post carefully, not much is changing for 8-16 core users. FreeBSD and SMP will continue to be supported. I wasn't referring to SMP at all when I was talking about Linux-only bits. > It should be easier to maintain a FreeBSD version as they (FreeBSD > developers) tend to aim for more consistency across releases than > Linux.

I know, I've fixed some things on OSX platforms via FreeBSD (OSX scares me with its GUI-ness). Keep in mind kqueue (and epoll) are worthless for Unicorn itself since Unicorn only handles one client at a time. However, Rainbows! can already use kqueue/epoll with EventMachine and Rev. > I don't want to start a flame war or say that one OS is better than > another. Linux is certainly great but so is FreeBSD. For the SMP part > I recommend the following page on freebsd.org: Again, I wasn't talking about SMP at all. SMP works fine on current Unicorn and mid-sized servers. When going to more cores, SMP itself is a bottleneck, not the kernel. With Unicorn 2.x, I'm targeting NUMA hardware that isn't available in commodity servers yet. Currently, NUMA makes _zero_ sense in web application servers, but in case things change in a few years, we'll be ready. It may be a chicken-and-egg problem, too. Hardware manufacturers are slow to commoditize NUMA because a good chunk of software can't even utilize SMP effectively :) > To conclude I can only say that I'm running unicorn on several FreeBSD > hosts and so far I couldn't be happier with it.

Again, don't worry :) You'll be able to continue using everything as-is. > Kindest regards and thanks for all you efforts, No problem. Please don't top post in the future. -- Eric Wong _______________________________________________ Unicorn mailing list - [email protected] http://rubyforge.org/mailman/listinfo/mongrel-unicorn Do not quote signatures (like this one) or top post when replying
