[systemd-devel] systemd-udevd: excessive I/O usage

Hello all.
while trying to optimize my bootup i noted that i could not squeeze it
under 17seconds userspace
Looking at the bootchart revealed that this is mainly due to
systemd-udevd consuming 60% of my bootup I/O.
This means i lose 12 seconds of bootup just to one process.
i was wondering whether there is any way to get this more optimized?
fewer udev rules? more readahead? something else? (i have no idea what
this I/O is, except for the fact that it is scattered all over the
place)
this was with systemd 184(from fedora18) on fedora 17.
