[SOLVED] Slow F17 on Mac Mini Server

[lrsas2]

I installed F17 Alpha on a Mac MiniServer today. I tried F16, but I ran into problems with screen jibberish, which is a know problem. So Anyway, F17 installed fine, but it took a while, like 4 hours!

I'm wondering if there may be a kernel option or module option that may help. If not, what kinds of things can I do to isolate the problem? The CPU is not busy-top shows nothing busy. There is not network connection, so it can't be net related. I will check the disk, but it doesn't 'sound' active, and I can hear it when its booting, so I don't think it's disk.

Any advice on things to do or check?

Thanks,

It's most likely due to the debug stuff in the kernel. Mine was also very slow until I recompiled the kernel without the debug info.

Get the kernel source and install it:
yumdownloader --source kernel
rpm -ivh kernel-*
Build it and install
cd $HOME/rpmbuild/specs
rpmbuild -bb --with release --without debug --without debuginfo kernel.spec
cd $HOME/rpmbuild/RPMS/...
rpm -Uvh --force kernel ...
(The installation takes a while so don't abort it)

Wow, so I hooked it up to the network and yum updated and the startup time went from 10 miuntes 28s to 2min 18s!!

I then followed Pauls seggestion and built a kernel with debugging disbaled and it went down to 1 minute 20s Startup time!!

Thanks Paul and all the developers of Fedora, this thing is rockin!
