Hi Mr. karua, Thank you for your bug report. However, we can not proceed with further processing of your report. We simply need a fully repeatable test case, which includes dumps of all the tables involved, as well as the full query itself. Without those, we can not proceed. We are waiting on your full feedback with all the data that we asked for.

The query am trying to run is SELECT * FROM finance_fees_statementv WHERE AdmNo like '11854'; takes less than a second on MySQL 8.0.27 AND More than 20s on MySQL 8.0.28

Hi Mr. karua, Unfortunately, we can not repeat your test case, since we are missing your table named `school_trackstudents`. Please send us that table, plus all the others that we are missing for this test .......

Hi, These are the mean values for 8.0.27, with three runs: real 0m1.418s user 0m0.013s sys 0m0.007s After I do all other preparatory work, I will report the values for 8.0.28.

Hi Mr. Karua, These are the mean values from three runs by 8.0.28: real 0m1.554s user 0m0.012s sys 0m0.007s As you can see those are all identical. You probably had another process running (like antivirus) while you were running 8.0.28. Not a bug.
