Diagnosing Slow Page Loads on Large Evolution CMS Sites with Ditto and YAMS
If a site with thousands of documents slows down dramatically, the cause is usually broader than one cache file and deeper than one snippet call.
Large Evolution CMS sites can slow down for several reasons at once: big document trees, heavy Ditto listings, multilingual processing through YAMS, and expensive output assembly on every request. When removing Ditto makes the site much faster but not fully healthy, that is a clue that Ditto is only one visible part of the performance stack.
Where the real cost often lives
- multiple listing calls on one page
- multilingual parsing and TV processing per item
- cache invalidation patterns that rebuild too much output too often
- large page trees combined with older snippet logic
On sites at this scale, performance work has to move from “which snippet is slow?” to “which combination of tree size, multilingual rendering, and listing strategy is multiplying the cost?”
