Sitecore Cache Tuning: LAYOUT_DELTA_CACHE

While tuning caches for a production level Sitecore 10.0.0 site, I came across a cache name I was unfamiliar with using a cache tunerLAYOUT_DELTA_CACHE

There were also log entries specific to this cache:

4484 12:07:57 INFO Cache created: 'LAYOUT_DELTA_CACHE' (max size: 50MB, running total: 6580MB)

Oddly enough, at the time of this post, no Google Search results mentioned this cache name.

Sitecore's documentation also had no mention of the setting either. 

Reaching out to Sitecore Support helped clarify things, and I wanted to share in case anyone else happens to come across this same cache that needs tuning. 

"The cache seems to be utilized when applying layout deltas when Sitecore is retrieving the layout field. The default size of this cache is 50MB, however, you can modify it with the "Caching.LayoutFieldDeltaCacheSize" setting."

Check out the following example configuration:

Hopefully, this helps with your Sitecore cache tuning activities. Happy tuning! 😊
