### Please describe the problem.
When I log in, if git annex is monitoring a large repo, my desktop is very sluggish getting started. Git-annex causes moderate CPU load, but keeps the disk IO very busy -delaying the opening of desktop applications.
### What steps will reproduce the problem?
On Linux, with git-annex set to autostart and monitoring a folder with more than a few hundred files (I have a pdf library of a few thousand journal articles).
### What version of git-annex are you using? On what operating system?
4.20131002 Ubuntu, from Hess's PPA.
### Please provide any additional information below.
I solved this problem by changing the call to git-annex in /etc/xdg/autostart/git-annex.desktop from:
Exec=/usr/bin/git-annex assistant --autostart
to
Exec=sleep 5 ionice -c 3 /usr/bin/git-annex assistant --autostart
This delays the start of git-annex for 5 seconds, letting the desktop get started, and forces git-annex to yield IO to other programs -preventing it from slowing them down by forcing them to wait for disk access. Since this is a background daemon with potentially high IO usage, but no need for quick responsiveness, perhaps that would make a decent default?
