Basically all I did was time the complete build prozess of a kernel: #!/bin/bash REV=`uname -r`-`date +%s` LF="/usr/src/logfile-$REV" PAR=100 tar xvIf /home/public/Linux/kernel/v2.4/linux-2.4.12.tar.bz2 >>$LF 2>&1 cd linux bzip2 -cd /home/public/Linux/kernel/v2.4/patch-2.4.13-pre5.bz2 | patch -p1 >>$LF 2>&1 bzip2 -cd /home/public/Linux/kernel/v2.4/2.4.13pre5aa1.bz2 | patch -p1 >>$LF 2>&1 patch -p0 < ../Makefile.patch >>$LF 2>&1 cp ../config-2.4.13-pre5aa1 .config (make oldconfig dep clean && make -j$PAR bzImage modules && cat /proc/loadavg && cat /proc/meminfo) > >$LF 2>&1 I ran the above script five times in a row after a fresh reboot into single user mode so that no other processes could interfere.
