I've just switched my firewall machine from RedHat 5.2 to Mandrake 8.2 with SNF. As part of my testing and to minimize firewall downtime, I did the installation and configuration on one machine and then moved the hard drive to the firewall machine. During this process I watched the system boot multiple times and noticed a couple of slow spots. First was kudzu. The hardware detection takes multiple seconds, i.e. there's a very noticeable delay. Seems to me that kudzu should be enabled when changing hardware and disabled otherwise. (In my case it was very useful as the configuration machine has a PS/2 mouse and the firewall machine had a serial mouse.) Second was ipvsadm. The boot process _usually_ takes a minute or so for "Applying ipvsadm rules from /etc/iptoip.xml". I haven't investigated this one. Third is generating modules.dep. The Mandrake kernels all have LOTS of modules. This generation process is _slow_ (on the Pentium 133). Using a custom kernel with many fewer modules, generating the file is much faster. I don't know if this information helps or not, but it's what I've noticed. David
