I've been noticing that my WeBWorK server feels a lot less responsive with 2.19 than previous versions.
Homework questions and answer checking seem fine, so the student experience should be OK.
But (for example) in the Sets Manager, if I click on the number of problems for a homework set (under the Problems) column, there's initially no response to the click, and it takes 5 seconds or more before the Set Detail page begins to load. Server side I don't see any issues with system resources -- memory, CPU, and load all seem normal.
Has anyone else encountered similar issues?
