Thanks for fixing this issue. Now, I'd like to know the performance impact this could have in the long run. Have you folks tested this with a more significant volume of users? Can the caching strategy time be set up to be lowered instead of removing it altogether?

@Lunyachek - do you know if this is still being pursued?

@mphilbrick211 I want to update and finalize the PR, but I have a problem with modifying this PR.

@mariajgrimaldi You're right, we have checked it on courses with around 1000 users, and removing this caching might affect the performance on the page, we decided to just set the default caching to 10 minutes (600 seconds).

I will reopen the same change in a new PR.
@mariajgrimaldi do you think opening PR against quince.master is still necessary since there won't be quince.4?

[Inferato]

@GlugovGrGlib I`m able to make these changes if it is ok for you.

[mariajgrimaldi]

@GlugovGrGlib: As you mentioned, if merged to quince.master, it won't be included in a new release. But folks could still use quince.master branch. If that works for you, I could review the PR. Let me know!

[mariajgrimaldi]

@Inferato @GlugovGrGlib: can we close this PR in favor of #34584?

[GlugovGrGlib]

@mariajgrimaldi yes, I'm closing it now!
