Does anyone have experience in using either of these? How much is the
performance different than the current init?
I use Initng. Is is running perfectly. In fact, a bug I had (where Esound would not start on booting as it should) was solved by moving from Sysvinit to initng.
The performance difference is large, but I don't remember the numbers. Just try for yourself.
On my Gentoo system, I have both Initng and Sysvinit. I choose on the Grub menu which one I'll boot. Initng is default. Sysvinit is there only because my friend Justin made me keep it.
Note: I'm using
initng-0.6.8.
Thanks,
KS.
