Yes, I’m certain that this is real issue, introduced in the KF6 port. I 
have tested with a build using the same settings for both versions.

Try this:

Download an example translation project:
svn co svn+ssh://svn@svn.kde.org/home/kde/trunk/l10n-support/nn

Fetch the old (KF5) Lokalize version using this command inside the 
Lokalize repository:
git switch --detach fb45c1ad

Compile and launch the application. Then open the project file 
nn/kde-nynorsk.lokalize, and time how long it takes to finish opening 
the project. The very first time, it may take an extra long time, so 
ignore this measurement. Close the project and reopen multiple times to 
get accurate measurements.

Then try the same using the new (KF6) Lokalize version (the next commit 
after fb45c1ad):
git switch --detach d59717e8

On my system, the KF5 version takes about 10 seconds to open the project 
(average of three measurements, ignoring the first after compiling). The 
KF6 version takes about 17 seconds, i.e. 70% longer.
