Steps to Reproduce:
1. Create a Blank Site "Prod Site"
2. Create a blank page in site "Prod Site" named "Prod Page"
3. Add and publish (60) "Tab" fragments to "Prod Page" (Search html for "component-tabs" to easily count)
4. (A new tab will be helpful) Enable and add a publication "Pub". Work on "Pub"
5. Create and publish a blank page in site "Liferay" (different site than "Prod Page") named "Pub Page"

Compare load times for "Prod Page" in Production (~2sec) vs Publication (~6sec)
I used: https://chrome.google.com/webstore/detail/page-load-time/fploionmjgeclbkemipmkogoaohcdbig?hl=en

6. Work on Publication. Add (1) "Tab" fragment to "Pub Page" and publish.

Compare load times for "Prod Page" in Production (~2sec) vs Publication (~50sec)
Summary: Create a page in Production with lots of tabs fragments. When you then create a page in a completely different site in a publication, when viewing the production page the load time is increased. Adding a single tab fragment to the publication page causes a huge increase in the load time for the production page when viewing it within a publication. Viewing the page in production is unaffected.
