Package time suddenly increase from 10min to 3+ hours 800mb project

Has anyone had this issue? Some time after updating from 4.14 to 4.17 my build time has changed from 10 minutes to 5+ hours.Is there a cache or something that needs to be cleared? The compile package is about 800MB and of of the other developers can publish in about 10 minutes still i seem to be the special flower of the pack…

So i found out that i had a drive that is dead. The drive being unreadable caused issues with the system packaging process. As soon as i removed the dead drive everything compiled properly.

Will try to remember to submit this to the bug section.
