Component weight check help

would you guys try to help me with test of dc of cabinnets? it is getting really heavy that even the selecting one of them is taking long time. after copying more of them its getting anoying.
thank for advices.
the components on the left are material info holders.component weight test.skp (6.6 MB)

Nevermind. I found the problem.
Attributes Dialoghight a DialogWidth were doing that delay. Just don use them . It slows down the dc a lot.
