We should see if the queries are slow enough so it's worth the pain of rewriting the classes.
|Duplicate||None||T52187 [[Special:UnconnectedPages]] insufferably slow when offset exceeds ~30k|
|Declined||Milimetric||T52195 Kraken data flow monitoring not working properly|
|Open||None||T96040 Wikibase special pages (tracking)|
|Open||None||T67168 SpecialWikibaseQueryPage has no caching|
|Resolved||Ladsgroup||T164906 Investigate performance of SpecialWikibaseQueryPage components without caching|
I made a list of slow queries in the past 48 hours in wikidata from tendril: P5411 (NDA'd, might contain private information). None of them has queries related to SpecialWikibaseQueryPage. There are some interesting things there though.
SpecialEntitiesWithoutPage responds in less than a second to me. LisProperties responds in 348 ms. And ItemsWithoutSitelinks in 536 ms.
Overall, I think everything is fine.
