CASE PM-112784-19-202375:

Previously, there were high response times when creating or modifying cases when email notification rules or item templates used the tag ** {{Description}} ** and the case description contained bulky HTML content, such as embedded images. The templating engine applied the tags one by one to the already modified text, so that each subsequent replacement had to go through increasingly extensive content. As a result, the processing time grew disproportionately to the size of the inserted content, and in some scenarios, the operation exceeded the maximum allowed execution time.

Tag replacement in email notification templates and the item merge engine is optimized, so that values resolve in a single run over the original template. With this setting, processing time is no longer dependent on the size of the embedded content, and case creation and modification retains stable response times, even when the description includes extensive HTML content.

⚐ Note: The tag ** {{Description}} ** can be used normally in notification templates, without the need to replace it with alternatives that omit HTML formatting.
