I need help! Well, you're not going to get much competition, so maybe help would be more in order ;-) ;-) Are you still doing something like this? # MAKE="make -j14" /usr/bin/time make -j14 bzImage I tried setting the MAKE variable as well as doing the -j, but it actually made kernel compile time slower - what difference does it make on your machine? Can somebody clarify what this actually does, as opposed to the -j on the command line? BTW - the other tip that was in the big book of whizzy kernel compiles was to set gcc to use -pipe ... you might want to try that. How much of that 7.52 seconds are you spending in the final single-threaded link & compress phase?
