Today I've upgraded to LSWS 5.4.6. After that, our XenForo forum encountered a bizzare bug. Threads with first visit were taking too much time to load! But once I got into the thread, it was fast during the revisit.
At first, I thought it was related to Redis cache, but no. Then I thought it was the XenForo 2.1.8 Patch 2 but then again, no.
After reverting back to 5.4.5, the problem was solved!
Here is the XenForo thread with a video showing the problem:
