[Koha] Switching from default to fast add framework is very slow...

Greetings, When adding a new marc record i usually change the framework from defauit to the fast add framework and it is extremely slow in the transition. It takes about 20 - 25 seconds just to change the framework. Any tips on how to improve the loading time. Running Koha version: 3.06.10.000 Previous versions loaded much faster than now Regards, Amir
