When you have lots of templates (e.g., in an --enable-extra-template build), starting soffice (to show the Start Center) has become very slow with the new Start Center, apparently because it unconditionally initializes information about all templates (BackingWindow::initControls calling BackingWindow::setupTemplateView, sfx2/source/dialog/backingwindow.cxx). (Even slower still on first start, when "The templates are being initialized for first-time usage.")
I did the test with a --enable-extra-template build. Starting soffice to show the StartCenter is as quick as before but the template manager is very loooooong to open, mainly the first time.

so as of comment #1 setting to NEW.
Confirming also on :

It takes a minimum of 50 seconds on my

to completely display the template manager window from first click on the Templates button in the Start Center.
The slow start leads to users clicking on the Template button multiple times, which in turn leads to bug 72587
StartCenter doesn't load templates autocratically any more and so this bug does not exist in this form.
There is an other bug about Template Manager loading slowness: https://bugs.freedesktop.org/show_bug.cgi?id=61471
So close this bug as fixed.
