Default Google Hangouts - unacceptable loading time

Had my N5 for quite a while now and I have only ONE issue with it - Hangouts. It takes ages to load, sometimes as much as 5 seconds. Every single other app is fine, but Hangouts just infuriates me. Am I the only person with this problem?

I'm running Cataclysm and Franco atm, but this was exactly the same when my phone was completely stock. I'm on Dalvik as well, because I can't give up Xposed.
