For all of you who are bothered by the performance of udev:
I did some profiling, where udev spents its time... so here are the numbers:
Out of 3.63s of measured activity udev spent:
44.1% (1,6s) with /sbin/modprobe
13.3% (0,48s) with persistent-storage (mostly vol_id)
12% (0.44s) with 60-net.rules
10.5% (0.38s) with 90-alsa.rules
7% (0.25s) with pam_console (which will go away anyway)
Your numbers may vary because of different hardware.
