Comment # 1 on bug 1169223 from Michael Andres

Somewhat depends on how one creates the locks. Every lock is basically a query. 
It will of course make a difference if you create ONE lock matching all
texlife-* packages

> # zypper al 'texlive-*'
> Specified lock has been successfully added.

> # zypper ll -m
> Loading repository data...
> Reading installed packages...

rather than the 6598 (on my 15.1) individual locks, which is most probably what
YAST did.


So if `zypper ll` shows you a few thousand texlive- locks, remove then and
replace them by one lock created by `zypper al 'texlive-*'` (I don't know if
YAST also has some API to create wildcarded locks). This should be much fater.
