When I used linux, which was while back, I would re-compile the kernel after installation is done for optimization. Is that still recommanded especially for opensuse?

For SUSE, no. You can do it, but support is not given from Novell/SUSE
if you do. Some gains may be found by doing this but unless you know
they will be significant I wouldn’t bother. If you are in the market
for a distro that is simply as fast as possible SUSE may not be what
you’re looking for or you may want to look into specific builds of the
kernel like the RealTime kernel that comes with SUSE’s SLES line. It
depends a lot on your needs, though. Most computers aren’t utilizing
100% of resources most of the time and with today’s computers all being
fairly fast (when new) I am not sure the benefits you can get from a
fully-optimized kernel will be worth the effort and risk. If so, Gentoo
is probably your friend.
Good luck.

Just to add a bit to the reply above . . . compiling custom kernels in a binary distribution requires really understanding that distro in depth. There are going to be kernel settings that are expected elsewhere in the distro. So, yes it can be done, but requires special care. So if this is something that is desired, it is better to go with a source-based distribution, in which case you are compiling not just the kernel but all the code to match the kernel. This is where the real performance gains come from, i.e., not just the kernel but also code optimized for that kernel. I used Gentoo years ago and I loved it (still do, for that matter). But it requires a lot of additional time and learning when you are building it all yourself.
Thanks for the insight info. That pretty much covered what I wanted to know. Thx!
