It takes disproportionately long to install www-apps/owncloud-6.0.x: Problem occurs right after this portage message: >>> Install owncloud-6.0.3 into /var/tmp/portage/www-apps/owncloud-6.0.3/image/ category www-apps With top on a different console, i could see nearly no CPU usage during this "break", sometimes a small peak of python. This happens on a fast System with SSD. But only for owncloud, other packages seems not to be affected. www-apps/owncloud-6.0.3 was built with the following: USE="curl mysql sqlite -postgres -vhosts" genlop -t owncloud * www-apps/owncloud Mon Jan 13 00:21:57 2014 >>> www-apps/owncloud-6.0.0a merge time: 16 minutes and 12 seconds.

Looks like bug #210575 or bug #465000. Any ebuild that uses `doins -r' is slow.
Nice catch, thank you very much Jeroen Roovers! I just disabled xattr Usefag for portage and now got this times: time emerge owncloud real 3m20.590s user 1m31.707s sys 1m21.696s Mon Jun 16 18:01:30 2014 >>> www-apps/owncloud-6.0.3 merge time: 3 minutes and 10 seconds. So i think i must wait until this https://bugs.gentoo.org/show_bug.cgi?id=511984#c1 is solved.
