Thanks for the post. I actually started working on this project late last night... My target test machine is an "getting old" Compaq R3000 with a 3ghz P4. What I'm going to do is just what you suggested. First I'm going to finish freshening the laptop. This is my daily "hack-n-slash" computer, so no worries clobbering it. I'm near the end of finishing an "emerge -e world" that was preceded with two rounds of "emerge -e system" Next step is some exhaustive bench marking. All suggestions welcomed. Then once completed, I'' make the change to chost from i686 to pentium4, following the docs on the net. Once done and smoothed out... another freshening as mentioned above, followed up with identical runs of what ever benchmarks I ran before... Should be interesting... It'll lay to rest what everyone speculates or postulates. :') Cheers. -- From the Desk of: Jerome D. McBride -- gentoo-user@lists.gentoo.org mailing list
