indeed on SLC5, but I don't think it's due to sudo. Apparently the slow-performance install-sh bash script is always chosen instead of /usr/bin/install, and is used to deploy a single file at a time (which are a lot if you consider format elements and webstyle icons...) It's something related to: <http://sourceware.org/ml/automake-prs/2005-q3/msg00008.html> $ # with automake-1.11 $ sudo -u apache time make install -j9 24.43user 5.51system 0:26.06elapsed 114%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+1405488minor)pagefaults 0swaps so ~30 seconds with newest autotools. $ # with automake-1.9 $ sudo -u apache time make install -j9 127.76user 20.07system 2:19.91elapsed 105%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+5401328minor)pagefaults 0swaps indeed it's 3 times slower :-) (actually install-sh is relying on /urs/bin/install to deploy a single file)... so almost 2 minutes and a half with default autotools on SLC5.
