I am a very happy openSUSE general user. This is my current desktop system: (CPU): Intel(R) Core™ i7-2600 CPU @ 3.40GHz; (RAM): 7.8 GiB; (GPU): GeForce GTX 560; (OS): Linux 3.7.10-1.40-desktop x86_64; (SYS): openSUSE 12.3 (x86_64) KDE: 4.10.5. It gets a lot of general use.
The system has been regularly upgraded (zypper dup) since 11.4 and I would now like to upgrade to openSUSE 13.1. However total boot and startup time relative to a fresh installation of openSUSE 13.1 on a separate partition on this machine, is getting a bit slow. So, I have a few general questions that I don’t want to bother the support forums with but I think may also be of interest to others.
How long to others persist with upgrades before doing a fresh install?
What techniques do others use to keep upgraded systems clean and efficient?
What issues (apart from backup) are likely to arise with a fresh install of openSUSE 13.1 retaining a current openSUSE 12.3 /home/user?
What tools are available to monitor boot and startup hogs?

I can’t see how to use Bootchart, but I know there are processes running from past ‘trial’ software installations that I don’t need. I have since learned to install such things on a ‘sand-box’ system for evaluation. Hint noted.

Thanks. That’s longevity. I read the referenced SBD with interest. Some good tips there.

Depends on how much customization I’ve done on the system and what
changes are in the upgraded system.
Usually 2-3, or I’ll try an upgrade, and if I’m not happy with it, I’ll
make sure my backups of /home are current, and I’ll do a fresh install.

Fresh installs every few releases, sometimes because I’ve migrated to new
hardware. Just went through this with my old “main” desktop - fresh
install on the new desktop, migrate /home over, then see what I missed in
terms of crontabs, extra non-RPM software installed, and other
customizations. Then wipe the old system and repurpose it or retire it.
A thousand times yes! The new system I got has an SSD on it along with a
large SATA drive. Shrunk the Win 8.1 installation to half the SSD and
put openSUSE 13.1 on the other half, with /home on a part of the large SSD
(2/3 to Linux, 1/3 to Windows - some Steam stuff is Windows only, after
all - and thanks to the Humble Bundles, I have a fair number of Windows-
only Steam games now).
Boot times on the new system are amazing - 5 seconds tops to a fully-
running system. It takes longer to get through the Dell BIOS startup
than to boot the system.
