I didn’t think this is worthy of a bug and I don’t have much real scientific evidence, but since upgrading to v2.3.0.beta10, I’ve noticed that threads are much slower to load.

I’ve noticed this on multiple forums hosted in different places (@v2.3.0.beta10 +28), even threads with only a couple of posts still take a second or two to fetch the posts.

This thread has 14k posts so it’s a dramatic example:

I also can’t find where to switch the mini-profiler on anymore, is that gone now?

No worries. I am pretty confident this is the issue you were seeing.
