XF 1.5 Site slow for users

So kind of posting here to hopefully get an idea of what might be going on.

For the last few weeks users on my Xen 1.5 forum has been having slow loading times on my site, many saying when login can take forever and then be fine. Far as configurations go, I haven't done anything to my forum in months if not a year, so this is basally a fine one moment and then an issue the next. Though I have had a few slow moments, I haven't experienced anything major myself.

I've reached out to my host, they say nothing is wrong and even transferred me to a less busier server and still have issues.

Someone thinks its because I'm still running php 5 instead of 7, which I can't run yet due to addon capability.


Anyone here have any clues?
 
Just to help out i think it's this place:
