Hello,
I recently switched from 13.1 to Tumbleweed and would like to make some remarks
- Booting takes a very long time, very much longer than with 13.1 and former versions. The hard disk is running like there is no end to it, longer than a minute, and when the graph working screen comes up, the HD still does not stop; it takes another 20 seconds or so before I can do anything. 13.1 did all that in no more than 20 seconds.
I remember reading systemd devs dropping support for read-ahead (which helped HDD performance). https://lists.freedesktop.org/archives/systemd-devel/2014-August/022002.html
- As I do not care for looking at an inert graph screen, in 13.1 I booted showing the text screen (splash=no quiet showopts silent), giving a nice sequence of the files that are loaded. In Tumbleweed I have the same GRUB setting, but I get just a few lines initially and then a black screen for the rest of the booting. However, I seem to belong to a minority, as apparently most prefer the graph booting.

- I understand that at booting a lot of services are loaded, apparently many more so than in 13.1, and I suppose that many of them are not necessary ones. However, I miss the possibility to have a look and switch off what I do not need; it would be nice to have something non-command line identical to services.msc under Windows (am I ignorant and is there?) for the non-essential and non-for-this-specific-hardware related ones. Which ones are specifically essential for each individual machine and can not be eliminated can be determined in the installation. That my idea is not so trivial is shown by the advice in https://lizards.opensuse.org/2012/07/26/optimizing-a-boot-time-aka-2-second-... from 2012, although that is quite extreme.
