Platform Performance Issues?

I checked a few of my apps across multiple Realms and they are all are flying fast with no issues.

I wasn't at the keys when you reported this, but for future reference, whenever we experience issues I'll check the Quickbase Service page. I don't see anything reported a couple days ago (when you posted this question).

You can subscribe to notifications too for both planned and unplanned activities.

If you continue to have performance issues, ask Customer Support. I've had the issue where my App gets put into a 'lane' (sharing resources) with another realm, and that realm is hogging resources (usually due to something wrong - a formula query too intense, a bloated app...>) and will slow down your realm. 

Or, make sure you didn't just recently make a big change that could be causing it. Most likely culprits recently - formula queries. But can be other things. You can ask Customer Support to see if they see anything in your app causing delays. Once they found in my app I had a search widget on a home page, searching like 700 fields at once. When people used it, it would hog all the resources. Simple fix, that I would have never known if I didnt ask.
