Plugin conflict w/ Query Monitor about rocket-lazy-load HOT 4 OPEN

I have discovered additional info, that maybe invalidates above hypothesis.

Our comments table is ballooning due to how some plugins store their metadata, and it turns out Admin Bar "Comments" menu item scans comments table on every request.

This becomes a massive performance bottleneck at hundreds of thousands of comments table rows, so I unhooked those menu items (source: https://gist.github.com/mattclements/10a997775894c7a0eba1)

I will also take a closer look at SAVEQUERIES next. It's likely this is not a JS topic at all.

Update: there's definitely something still going on. Investigation continues.

2.0.2: things seem better here. Will report back in about 2 more weeks, so the experience sample size becomes adequate.

rocket-lazy-load-2.3.0.2
query-monitor-3.2.2

This is now confirmed to still be a problem, with plugins at their latest versions, but surprisingly only on Chrome.

All other performance issue vectors are confirmed to have been eliminated.

Firefox-64+ seems to somehow manage to avoid this issue.

PS 2.3.0.2 is missing its github tag.
