Query updates for performance #215
Comments
Full log including queries and errors is attached here. |
Additional information: Using the updated query performance script that takes a course id and filters to that course (the way these dashboards are intended to be used) we've got better numbers (using a "huge" load test course on the same dataset):
The only report that got killed for memory was "Watched Video Segments":
Interestingly this consistently loads in the UI. "Distribution of Current Course Grade" consistently failed, or returned no data in 0 seconds in spite of it actually returning data in the dashboard. Full log: |
Problem interactions and problem results are that slow? Really? Should we close this one and open a new one for Sumac? |
Yes, we should see more recent performance. Some of the performance issues here are what I was talking about when I said that the performance script doesn't line up with what we actually see in Superset. I'm not sure where the problem lies currently, but we should use a combination of both to find the slowest queries we'd like to work on and not rely just on the script. |
