Me, too. > You might be able to see some of the processes running using top. You > could always stop apache. True, I could do that, but what is your opinion on running the entire build/install process from single-user mode? (my original question) > I kind of wonder if you have cache turned on in the cpu.

Oh, geeeez, technical stuff! ;-) I'm a real dumbass in the BIOS. I just select "Load High Performance Settings" on each machine, and then change the boot order to my liking. I did notice that 'internal cache' is set to 'write-back'. Am I on the right track? *Exactly* how do I watch the swap...in top? _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
