FYI, there a couple more slow than query 24: ``` │ QQuery 26 │ 228.11 ms │ 324.39 ms │ 1.42x slower │ │ QQuery 10 │ 363.24 ms │ 484.80 ms │ 1.33x slower │ │ QQuery 7 │ 54.19 ms │ 68.48 ms │ 1.26x slower │ │ QQuery 25 │ 489.11 ms │ 617.52 ms │ 1.26x slower │ │ QQuery 11 │ 427.02 ms │ 532.87 ms │ 1.25x slower │ ``` -- This is an automated message from the Apache Git Service.
