Martin et al:
Here is a litle bit more information: 2.6.7-mjb1 w/4G split enabled: 44.91user 56.95system 1:46.30elapsed 95%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6907875minor)pagefaults 0swaps
2.6.7-mjb1 w/4G disabled enabled: 30.71user 34.56system 1:11.29elapsed 91%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (21major+6907525minor)pagefaults 0swaps
Clearly something is wrong. This is making headers which does a lot of spawning of bash shells and ln -s different files and some minor dependancy makes. Any help understanding what is happending here would be greatly appreciated!
Thanks! Phy
