Depends on what you're doing, I suppose. The make world process is particularly disk intensive. On the other hand, formatting my "Introducing FreeBSD" book is *much* faster on a Pentium. On a P5/133 with 64 MB running BSD/386 1.1, I can format the book in about 60 seconds. On the 486/66 with 32 MB, running FreeBSD-current, it takes 240 seconds. OK, we have different OSs here, and the 486 has less memory, but I don't see much paging activity on the 486, and I don't really think the OS makes that much difference. One day I might get bored enough to make a real comparison. Greg
