[Wikidata-bugs] [Maniphest] T265562: [6hr.] Investigation - Wikibase Lua: addStatementUsage seems unjustifiably expensive

Lydia_Pintscher closed this task as "Resolved". Lydia_Pintscher added a comment. I checked it again now and the addStatementUsage part takes 860 ms. While this is still large and we should improve it I am going to close this ticket because the spike seems to be gone and have been an issue

toan added a comment. We discussed the way forward for this task this morning and decided we will not spend more time investigate what could have been the root cause now ( even though it would be very satisfying ) but keep this ticket on the board and monitor if there any changes in the

RolandUnger added a comment. I was surprised, too. And I did not made any changes (yesterday morning I only added some maintenance categories). The computing times for `addStatementUsage` oscillate (between 400 and 900 ms) but they are clearly reduced. I think yesterday the 1.36.0-wmf.14

RolandUnger added a comment. I am not sure if T263999 is the real cause for this bug. But I cannot exclude this cause, or maybe both bugs have a joint cause elsewhere. `addStatementUsage` only registers the use of an entity and a property and has
