The source code for FreeBSD is a direct decendant of the BSD branch of Unix developed at the U of California at Berkeley. Linux was developed "from scratch" by Linus and his associates in the 90's. BSD dates back to the early 80's and is a more mature OS. Linux is amazingly good for a recently written OS. It has certainly won the popularity contest! I have two old 486 machines that I use for playing with various stuff I'm working on. They are both 486's, one a 100mhz dx-4 running RedHat 5.2 and the other is a 66 mhz dx-2 running FreeBSD 3.1-RELEASE. Both have 16 megs of memory and IDE drives. The FreeBSD machine with the slower processor is much quicker to boot and load programs. I think that it is because the Linux machine's free memory is less, due to a larger kernel and the VM is not as efficient, as both machines swap like crazy when you start up big executables like Netscape 4.5, but the FreeBSD machine gets it "on the screen" in roughtly half the time. The Linux box is very stable and seems to have a very nice "native" installation setup. I intend to swap the drives to see if there is actually something wrong with the hardware, but for right now, the FreeBSD box is much more lively with that very limited hardware. I suspect with more RAM and faster swap devices, the Linux box would run much better. If you'd like, I'll run something that does some number crunching and see what the results are. regards, Jim Durham To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
