Just because you finally chose Managed WordPress hosting, doesn’t mean you’re completely out of the woods.
There’s always room for improvement.
You might think, “Hey, aren’t I supposed to be all set with my hosting if I use something that’s supposed to be better like managed WordPress hosting?” Yes, you’d be correct to assume that. The setup is better, but you can always tweak.
I thought it was funny because I did a Google search for “increase memory on managed WordPress hosting GoDaddy” and got this (screenshot).
Which led me to, ahem, my own site here because, apparently, I had this issue in the past (Increase memory limits on GoDaddy’s Managed WordPress hosting). So it seems that just because you have great hosting, doesn’t mean you can’t tweak a few things and improve speed still even more. I suppose you could also contact the host to have them do this, but if you know how to get into your site files, you can make this change and fix your memory limits right then and there.
