Opencart reduce load time while fetching too many data's from database - loading

Question

I'm using attribute filter option in my store. For this i'm using below codes in admin view template. This'll fetch all attributes form database and using jquery tabs i'm hiding all inactive ones.
The weired problem what i'm facing is LOADING TIME . I'm having more than 5k products in my store. SO retrieving all attributes taking long time(I think so). Did anyone have any idea to reduce loading time in this case?
