Installation and the 1024 cylinder boot problem

Recently I had to install 5.1-RELEASE at 60GB, and had a lot of troubles to start booting correctly. I hope that /stand/sysinstall have to handle >1024 cylinder booting. Otherwise I have to run 'boot0cfg' manually to fix this issue. MuTk0 ___ [EMAIL

Re: Swapping performance

in algorithms for making automata's. And when we saw that one think on Linux was done for a few hours, but on FreeBSD much, much more, I start tests to investigate where the problem is. This test (malloc_test) is the first think that gives serious difference and I thought that the problem is in swapping o

Magic number 100 in /sys/kern/kern_fork.c

I've review /sys/kern/kern_fork.c file and have a question why the room of 100 process numbers is hardcoded in the source? I think that if such room is needed, it must be defined somewhere in headers, isn't it. Can someone explain me more the idea about that room? -- Dimitar Peikov
