MGNLPN-560 introduced a new CachingVariantAwareTitleColumnDefinition. However, this column can still be slow in some systems.
Can we improve performance if component variants are not used? There should be some setting on the column class to turn off the component variant query.
For the release notes (if spotlighted):
The CachingVariantAwareTitleColumnDefinition class has been optimised for personalised pages to render variant icons even more efficiently by keeping track of pageIdentifiers that are not stored in the user session cache.
Also noting that it's only mentioned in the RN for 6.2.11: https://docs.magnolia-cms.com/product-docs/6.2/Releases/Release-notes-for-Magnolia-CMS-6.2.11.html#_notable_bug_fixes and in the nexus so far.
