MOODLE_311_STABLE
The performance jobs started failing consistently. For instance: https://ci.moodle.org/job/P.00.00%20-%20Attic%20-%20Performance%20comparison%20moodle.git%20vs%20integration.git%20(master)/2320/console
There is an increment on db queries and on time used:
Summary (comparing normalized runs)
|
between before - 400 (a5f0b354e7e weekl...) and after - 400 (e61f3796ddb Merge...) |
(Normalized) - increment: dbreads - All steps data combined -> 4.49% worse |
(Normalized) - increment: dbquerytime - View course -> 35.55% worse |
(Normalized) - increment: timeused - View course -> 34.61% worse |
After bisecting, the first bad commit points to MDL-71235:

MDL-71235 webservices: add activity completion data to web services |
After applying MDL-71235, these are the numbers I'm getting in my local instance with a Course M:
- Time: 1.964736 secs
- DB queries: 0.60742 secs
- db reads/writes: 875/3
And without this patch (so using the previous commit to this , e42ce0baeea5cc90e7512ee9cb95f9dbd50e332d) I'm getting:
- Time: 1.097802 secs
- DB queries: 0.22227 secs
- db reads/writes: 565/1
