Would you like to suggest a link, from where i can download the script ?
Sorry, the whole thing was quite messy and I didn't find the time yet to change it.

Maybe you can make sense of these:

to do the runs and get the data:
for nice in 0; do for run in $(seq 1 5); do for j in $(seq 1 10); do echo "building with nice=$nice, j=$j, run=$run" >> timelog; /usr/bin/time -a -p -o timelog nice -n $nice make buildworld buildkernel -j $j >/dev/null 2>&1; [ $? -ne 0 ] && echo "fail" >> timelog; done; done; done
ruby -ne 'BEGIN{$a=Hash.new{|h,k|h[k]=Hash.new{|h,k|h[k]=[]}}};if $_ =~ /nice=(\d+).*j=(\d+).*run=(\d+)/; $nice,$j=$1.to_i,$2.to_i; end; next if $nice != 0; if /^(real|user|sys)[[:space:]]+([\d.]+)/; $a[$j][$1] << $2.to_f; end;END{print "# ";$a[$a.keys[0]].keys.sort.each{|t| print "\t#{t[0...3]} min\t#{t[0...3]} max\t#{t[0...3]} med"};puts;$a.keys.sort.each{|j| h=$a[j]; print "#{j}"; h.keys.sort.each{|t| a=h[t].sort; print "\t#{a[0]}\t#{a[-1]}\t#{a[a.length/2]}"}; puts}}' < timelog |tee ~/tmp/m
ake-j-runtimes
the gnuplot script for generating the graph is attached.  you use it by running gnuplot and then:
set terminal png
set output 'make-j-runtimes.png'
load 'make-j-runtimes.plt'
quit
I think you'll want to change the $(seq 1 10) to $(seq 1 5) if you're testing this on a 2-way machine, and to $(seq 1 3) on an UP machine.

Let me know if you have any questions.

cheers
