RolandUnger added a comment. The Wikivoyage template vCard can use up to 50 statements per template (see table ParWD at Module:VCard/Params , too). About 5 `addStatementUsage` calls per template

RolandUnger added a comment. If the bug is caused by cache limitations: Maybe a simple destructor `entity:remove()` would help. People told me that all entities are cached until the end of article parsing. But most of the entities are used in only one template and must not be cached any

RolandUnger added a comment. I tried to remove the museum section from https://de.wikivoyage.org/wiki/Halle_(Saale) and to stop using qualifiers and references from entities but the bug remained. But it seems that this bug depends on the number of entities loaded: -

RolandUnger added a comment. It seems that it is a sudden spike. The computing time only for `addStatementUsage` jumped from about 600 ms to 5000 ms (all Lua stuff from about 4.5 sec to about 9 sec). Within the last two weeks I added and optimized the analysis of opening hours to our vCard
